Air circuit breakers can be used both as circuit-breakers for general protection (of plants, of user complexes, of electric lines) and as protection circuit breakers of electrical machines (generators, motors, transformers, capacitors).

These can be used both as circuit-breakers for general protection (of plants, of user complexes, of electric lines) and as protection circuit-breakers of electrical machines (generators, motors, transformers, capacitors). They are used in all types of plants (civil, industrial, and in the service sector) as well as in the equipment on-board ships, in mines, in prefabricated substations, and for primary and secondary distribution in general.

Specific characteristics
All the SACE Emax circuit-breakers except for Emax X1, have the same height and depth both in the fixed and withdrawable version and allow construction of compact switchgear.
They are fitted with many features which mean the personnel can always work under conditions of maximum safety, such as racking-out with the door closed, degree of protection towards the outside up to IP54, an articulated series of safety locks and double insulation.
The innovative structure of the pole guarantees complete insulation between phases and between phase and neutral and ensures full possibility of inspection of the arcing chamber and the main contacts.
SD Pocket is an innovative function which means a PC, even a hand-held one, can dialogue with Emax by means of the Bluetooth protocol. By means of the PC, and without any cables, the following is now possible, for example: the setting of the various protections, display of the measurements including those stored in the Data Logger, to verify the state of the circuit-breaker, know the number of operations carried out, etc..

Conformity with Standards
The SACE Emax circuit-breakers and their accessories are according to the international IEC 947, EN 60947 (harmonised in 28 countries of the CENELEC), CEI EN 60947 and IEC 1000 Standards and conform to the EC Directive:

"Low Voltage Directives" (LVD) no. 73/23 EEC
"Electromagnetic Compatibility Directive" (EMC) no. 89/336 EEC.
Furthermore, a series of SACE Emax circuit-breakers conforming to the UL 1066 Standards is available.

Low voltage selectivity with circuit breakers

The moulded-case circuit-breakers, proposed by ABB SACE, derive from two families of apparatus: the well-known and consolidated Isomax S series and the recent but already much awarded Tmax series (Top selection at Intel Design 2003 for their technological content and respect of the environment ). In particular, Tmax are characterised by an extremely high level of performances with limited overall dimensions, installation simplicity and an increasingly greater guarantee of safety for the operator thanks to their reinforced insulation. Tmax circuit-breakers, thanks to their performances, completeness of protection releases and accessories, can be used for all distribution and sub-distribution application for both AC and DC electrical plants.

Specific characteristics of Tmax
The Tmax series is characterised by being a product with a high technological content - the fruit of the most advanced design and simulation tools with excellent performances in minimum overall dimensions.

Thanks to the new technology used for the arcing chambers and the speed of contact opening, the circuit-breakers of the Tmax series guarantee strong limitation of the specific let-through energy and reduction in the peak currents, therefore limiting overheating of the devices and electro-dynamic stresses.

Furthermore, the new Tmax circuit-breakers use a completely common and standardised range of accessories with considerable advantages in terms of reduced stocks as well as flexibility and ease of use. Then within this range there are also the new residual current releases up to 500 A.

Field of application
The moulded-case circuit-breakers are used in industrial and civil low voltage plants with service currents from 1 to 1000 A. They are used in direct and alternating current distribution switchgear, for motor protection (Motor Control Center), generators, capacitors and for end users.

RCCBs are only sensitive to current leakage to earth. They must be used in series with an MCB or fuse which protects them from the potentially damaging thermal and dynamic stresses of any overcurrents.

These devices are used in systems already equipped with MCBs which preferably limit the specific energy passing through, also acting as the main disconnecting switches upstream of any derived MCBs (e.g. domestic consumer unit).

Manual Motor Starters (MMS) are protection devices for the main circuit. They combine motor control and protection in a single device. MMS are used mainly to switch motors manually ON/OFF and protect them and the installation fuse less against short-circuit, overload and phase failures. Fuse less protection with a manual motor starter saves costs, space and ensures a quick reaction under short-circuit condition, by switching off the motor within milliseconds.

ABBs Manual Motor Starters can be equipped with many other accessories. Connection links ensure that the ABB Manual Motor Starter can be connected to ABB Block Contactor and Soft starters easily and wiring-free.

Characteristics of Manual Motor Starter range

Thermal overload relays are economic electromechanical protection devices for the main circuit. They offer reliable protection for motors in the event of overload or phase failure. Starter combinations are setup together with block contactors and mini contactors.

The thermal overload relays are three pole relays with bimetal tripping elements. The motor current flows through the bimetal tripping elements and heats them directly and indirectly. In case of an overload (over current), the bimetal elements bent as a result of the heating. This leads to a release of the relay and a change of the contacts switching position (95-96 / 97-98).

ABB Softstarters – the complete range

PSR — The compact range
The PSR softstarter is the most compact of all the softstarter ranges, thereby making it possible to design compact starting equipments. The system concept with Manual Motor Starters and the PSR provides a far more compact starting solution than for instance a star delta starter. Built-in by-pass reduces the energy loss and makes the connection easier and with only three potentiometers, the set-up couldn’t be any easier. Still, the optimized ramping characteristics will ensure a very smooth start and stop for all applications.

PSS — The flexible range
The PSS softstarter allows both in line and inside delta connection making it a very flexible option. Just as on the PSR softstarter, the few settings make the set-up very easy. Connecting an external current transformer makes it possible to activate the current limit function, which will allow you to keep the current at a pre-set level also when starting heavy duty applications. The PSS softstarter is the ideal solution when looking for a robust solid state starting solution where many starts per hour are required.

PSE — The efficient range

The PSE softstarter is the world’s first compact softstarter with both built-in electronic overload for motor protection and torque control for an excellent control of pumps. The compact design with the most important functionality integrated provides a very efficient starting solution. The illuminated language neutral display and the four button keypad make it easy to take advantage of all the advanced functionality in the softstarter. The display will also provide all the necessary information both during ramping and continuous operation.

PST(B) — The advanced range

The PST(B) softstarter is the most advanced softstarter in the range with almost all imaginable functionality included. All the advanced protections for the motor, the softstarter and the load ensure a trouble free operation. Pre-warnings even allow problems to be detected before the motor needs to be stopped and thereby avoiding unnecessary downtime. The torque control function has been developed and tested together with well known pump manufacturers to ensure the absolutely best possible stop of pumps without water hammering and pressure surges. With the full text LCD display in your own language, pre-programmed application settings and event logging, it couldn’t be easier to set-up and operate. By using the ABB FieldBusPlug, you can decide at any time which bus protocol to use. The fieldbus system will allow you to set-up, control and monitor the softstarter.
