Circuit breaker 4P, 25kA, TM EB2 125/4L 125A 4P 004671032

Compact circuit breakers – reliable installation protection

EB2 compact power circuit breakers are a proven solution for protecting electrical circuits. They provide effective protection of cables, power cords, motors and electrical equipment against the effects of overloads and short circuits. The device is designed for circuit switching and is a key element of every safe electrical installation.

This circuit breaker, with a rated current of 125A and a short-circuit breaking capacity of 25kA at 400V, guarantees a quick response in emergency situations. The device's lever-based design ensures intuitive operation and easy switching. The four-pole design (4P) allows for the protection of multi-phase circuits.

### Construction features and application

The EB2 125/4L circuit breaker is characterized by a wide setting range for the overload release (78.8…125A) and short-circuit release (750…1250A), allowing for precise adaptation to the specifics of the protected installation. The ability to adjust the thermal and electromagnetic protection current – or select a characteristic for the electronic version – increases the device's flexibility. This allows you to adapt its operation to specific needs and working conditions.

The built-in trip indicator informs about the operation of the protection, making it easier to diagnose problems in the installation. The IP20 degree of protection provides basic protection against contact and ingress of solid objects. The circuit breaker is designed for permanent mounting, and an optional motor drive enables remote control. The connection of the main contacts is made using screw connections, ensuring a secure and durable electrical connection.
