Power switch 3P, 25kA, TM EB2 400/3L 250A 3P release 004671091

Compact power circuit breakers – reliable installation protection

This three-pole EB2 250/3L power circuit breaker with a rated current of 250A and a short-circuit breaking capacity of 25kA is a solid solution for protecting electrical circuits. It is suitable for both industrial installations and public buildings, ensuring safety and continuity of power supply. The device is designed for connecting and protecting cables, power leads, motors and electrical equipment from the effects of overloads and short circuits.

Construction and operating parameters

The circuit breaker is characterized by universal mounting – it is a fixed-mounted device. It has a screw connection of the main contacts, which facilitates the connection of wires. The tripping indicator allows for quick identification of the device status. Thanks to the adjustable setting range of the overload release (157.5 - 250A) and short-circuit release (1500 - 3000A), the circuit breaker characteristics can be adapted to the specifics of the protected installation. The IP20 degree of protection provides protection against touch and limited protection against environmental influences.

Functionality and application

The EB2 circuit breaker offers a wide range of expansion options thanks to available additional equipment: overcurrent releases, undervoltage releases, remote control, motor drives, auxiliary and alarm contacts, and mechanical locks. The ability to mount motor drives or remote control increases user comfort and enables integration with automation systems. SP2 cage clamps and ZB2 busbar connections are also available, providing flexibility in connecting wires of different thicknesses. These circuit breakers comply with the PN-EN 60947-2 standard, guaranteeing their safety and reliability.
