Circuit breaker 4P, 36kA, TM EB2 125/4S release 125A 4P 004671052

Compact power switch for installation protection

The EB2 125/4S power switch is a reliable device designed to protect electrical circuits against overloads and short circuits. It provides effective protection for cables, power cords, motors and electrical equipment. The device's construction, based on proven technology, guarantees long-lasting and trouble-free operation. It is a four-pole switch with a rated current of 125A and a short-circuit breaking capacity of 36kA at 400V, making it an ideal solution for both commercial and industrial installations.

Functionality and application

The EB2 125/4S switch is widely used in public buildings, industrial plants and in home installations with higher power demand. The ability to adjust the thermal protection current (78.8…125A) and short-circuit current (750…1250A) allows for precise adaptation to the specifics of the protected installation. This ensures that the device minimizes the risk of unnecessary circuit tripping during short-term overloads, while providing effective protection against serious failures. Equipped with a lever, it allows for quick and intuitive control.

Construction features and additional possibilities

The switch has been designed with ease of installation and operation in mind. The possibility of mounting on a plate or on a TH rail (using an adapter) increases installation flexibility. It has a protection class of IP20, which provides basic protection against contact and ingress of solid objects. Additionally, the switch is compatible with a wide range of accessories – overcurrent releases, undervoltage releases, remote control or motor drives – which allows to expand the functionality of the device according to individual needs. The trip indicator informs about the operation of the protection, making it easier to locate the problem in case of a failure. The connection of the main contacts is made using screw connections, which ensures a secure and durable connection of the wires.
