Power switch 3P, 36kA, TM release (magnetic adjustment) EB2 800/3LF 800A 3P 004672204

Reliable power protection – circuit breaker EB2 800/3LF

This three-pole circuit breaker with a rated current of 800A is a solid solution for protecting electrical installations against overloads and short circuits. It is suitable for protecting cables and power supply lines, as well as motors and electrical equipment. The EB2 circuit breaker combines reliable operation, a wide range of adjustments and the possibility of expansion with additional functions.

Functionality and flexibility

The circuit breaker is characterized by magnetic adjustment, which allows you to adapt the tripping characteristics to the specifics of the protected installation. Thanks to this, the device reacts quickly to short circuits, and at the same time tolerates short-term current surges during the starting of motors or other loads with high power consumption. The rated short-circuit breaking capacity at 36kA at 400V ensures effective protection even in the event of serious disturbances in the network.

Installation and expansion

The installation of the circuit breaker is simple and intuitive – the device is designed for mounting on a plate. The availability of a wide range of internal accessories (overcurrent releases, undervoltage releases, remote control, motor drives, auxiliary contacts) allows you to adapt the functionality of the circuit breaker to individual needs. The possibility of using mechanical locks increases work safety and prevents accidental disconnection of the circuit. The connection of the main contacts is realized by screw connections.
