Overcurrent circuit breaker, 10kA BKH series 3P 100A characteristic D BKH 3P D100A

Overcurrent circuit breakers of the BKH series – reliable installation protection

The BKH series overcurrent circuit breaker is a three-pole device designed to protect electrical circuits against overloads and short circuits. Model BKH 3P D100A, with a rated current of 100A and D characteristic, is perfect for applications requiring high resistance to surge currents. This is particularly important when protecting circuits supplying devices with high power consumption during start-up, such as motors or transformers.

Characteristics and application

Characteristic D means a delayed response to current increase, which allows for safe starting of devices generating high surge currents without unnecessary tripping of the circuit. BKH circuit breakers are designed for mounting on DIN rails and are widely used in building, industrial and building automation installations. They provide effective protection against the effects of failures, minimizing the risk of equipment damage and fires. A wide range of operating voltages (230/400V AC) makes it a universal solution for various installations.

Construction and user features

The BKH 3P D100A circuit breaker is characterized by a solid construction and high quality workmanship. It has a visual indication of the contact position, which facilitates quick identification of the circuit breaker status. The housing with a protection degree of IP20 provides basic protection against touch and ingress of solid objects. The possibility of connecting wires with a cross-section from 1 to 50 mm² provides flexibility in choosing the appropriate cables for a specific application. The short-circuit breaking capacity of 10kA guarantees effective protection even in the event of serious disturbances in the electrical network. The device operates in a temperature range from -5°C to 40°C, which allows it to be used in various environmental conditions.
