The S2 Series of ABB miniature circuit breakers offer a compact solution to protection requirements. The S2 devices are current limiting, DIN rail mounted and can offer a good equivalent to fused systems. The S2 is available with application-specific trip characteristics to provide maximum circuit protection. The breakers offer thermal-magnetic trip protection according to B, C, D, K and Z characteristics.

The S500 heavy-duty circuit breaker fulfills these requirements by virtue of its technical features. It is equipped with a thermal and/or electromagnetic release to protect circuits, motors, switchgear and systems from the effects of overload and short-circuit currents. For the worldwide market, the S500 breakers carry UL, CSA, IEC, CE and many other agency approvals.

ABB High Performance MCBs of the S800S series limit energy and power in the event of a short-circuit cut-off. The specially developed double arc chamber system ensures these outstanding operating properties.

Molded Case

Tmax moulded-case circuit-breakers guarantee an extremely high performance level while being progressively smaller in size, simple to install and able to provide increasingly better safety guarantees for the operator. In addition to being ideal for the secondary distribution of alternate and direct current, they feature dedicated solutions for all application requirements. Moulded-case circuit-breakers can be used in low voltage civil and industrial installations with 1 to 3200 A operating current. The Tmax family includes 9 circuit-breaker sizes in three- or four-pole versions.

ABB's FORMULA molded case circuit breaker line offers simplicity and quality in some of the smallest dimensions available. The A1 breaker frame size ranges in amperes from 15 through 100 and the A2 breaker frame size ranges from 125 through 250 amperes. All UL FORMULA circuit breakers offer protection trip units that have fixed thermal and magnetic threshold values and are standard as a fixed version with front terminals.

Circuit Protection Devices

Residual current devices, RCDs, provide ground fault equipment protection by monitoring the leakage of current to ground. The F200 series will trip when ground faults are detected in excess of the residual current trip rating of the device.

In order to ensure protection from transient surges, installation of surge protective devices (SPD) is a must. ABB has a long history of engineering and manufacturing quality surge protective devices.

E 90 series fuse switch disconnectors are designed for switching circuits under load, providing protection against short circuits and overloads. E 90h fuseholders are suitable for protection against overloads and short circuits.

E210 series command devices are specifically made for commanding loads and signalling electrical conditions in any low-voltage switchboard.

Air Circuit-Breakers

Air circuit-breakers can be normal, current-limiting, selective and selective current-limiting. Current- limiting circuit-breakers are those that, in the event of a short circuit, are able to limit the let-through current to a value that is lower than the prospective value. This characteristic enables important economic savings to be made when constructing both circuit-breakers and the busbars and conductors that they protect.

Selective circuit-breakers are circuit-breakers that are able to withstand high let-through currents for longer times than those normally needed to open a circuit-breaker, thereby enabling downstream circuit-breakers to trip. The tripping of the protection circuit-breaker that is electrically nearer to the fault guarantees the continuity of service in the rest of the installation. Selective, current-limiting circuit-breakers combine the characteristics of the two families. These circuit-breakers, by exploiting the current-limiting capacity, cause an increase in their resistance to the specific let-through energy, making them therefore able to withstand the fault current for the time needed to guarantee selectivity of the installation.

High Performance

SMCBs are selective main circuit-breakers (SMCB) for overload and short-circuit protection in electrical installations. They offer total selectivity to downstream mcbs and outstanding selectivity to upstream protective devices due to unique current limiting selectivity. The S500 and S800 are High-performance circuit breakers for overload and short circuit protection for electrical equipment. Due to to the wide range of rated current of 0,1A to 125A, they are an ideal solution for AC and DC application. The high breaking capacity of up to 50kA makes a calculation of the short circuit current almost redundant.

Manual Motor Protectors

Manual motor protectors are electromechanical devices for motor and circuit protection. These devices offer local motor disconnect means, manual ON/OFF control, and protection against short circuit, overload, and phase loss conditions. Manual motor protection saves cost, panel space, and ensures quick and reliable short-circuit protection by reacting within milliseconds. Close coupling adaptors are available for combination with ABB contactors in various applications. ABB manual motor starters provide overload protection as required by Article 430 of the National Electrical Code.

IDEC Breakers

The NC1V Series breakers employ an electromagnetic tripping system, where the rated current (trip current) is not affected by ambient temperatures. But the time delay may vary with the oil viscosity in the oil dash pot. Lower oil viscosity at higher temperatures results in a shorter delay, whereas at lower temperatures the delay will be longer. Inertia delay is designed not to trip on a non-repeating single pulse of 20 times
