Overcurrent circuit breaker, 10kA series BKH 4P 63A characteristic D BKH 4P D63A

Protection of installations and devices – circuit breaker BKH 4P D63A

This four-pole circuit breaker from the BKH series with a rated current of 63A and characteristic D is a solid solution for protecting electrical circuits. Designed to protect against the effects of overloads and short circuits, it ensures reliable operation of installations in residential and industrial buildings. Characteristic D means that this circuit breaker is intended for circuits with high surge currents, such as those occurring when starting motors or other devices with high power consumption.

Application and functionality

BKH circuit breakers are widely used in building automation and in industry. Their task is to protect wires and connected devices from damage caused by overload or short circuit. The four-pole construction means that this circuit breaker can protect multi-phase electrical circuits. Characteristic D allows for momentary exceeding of the rated current without unnecessary tripping, which is particularly important in the case of devices with induction motors.

Construction and parameters

The BKH 4P D63A circuit breaker has been designed with durability and reliability in mind. Its construction ensures stable operation in various environmental conditions. The rated current of 63A makes it suitable for protecting circuits with medium power consumption. These circuit breakers are available in configurations from 1 to 4 poles, allowing them to be adapted to specific installation needs. A wide range of currents (up to 125A in the BKH series) and the availability of characteristics B, C and D allow for flexible configuration of protection systems.
