Overcurrent circuit breaker, 6kA series BKN 4P 20A characteristic C BKN 4P C20A

Safety and electrical installation protection

The BKN series overcurrent circuit breaker is a reliable element protecting electrical installations against overloads and short circuits. The 4P model with a rated current of 20A and C characteristic provides effective protection for circuits where loads with motors or other receivers generating high inrush currents during start-up occur.

This four-pole circuit breaker, thanks to its C characteristic, allows for short-term exceeding of the rated current without unnecessary tripping of the circuit – which is particularly important in the case of devices with motors, transformers or impulse power supplies. This reduces the risk of false alarms and downtime of devices.

Design and application

The BKN 4P C20A circuit breaker is designed for mounting on a TH35 rail. Its compact dimensions allow for efficient use of space in the distribution board. The rated short-circuit breaking capacity of 6kA guarantees safety in the event of a serious failure.

• Application: ideal for protecting lighting circuits, socket circuits and electrical devices with a characteristic power demand during start-up.
• Mounting: quick and easy mounting on a TH35 rail – saving time for both the installer and the end user.
• C characteristic: provides protection against overloads and short circuits, while allowing for short-term current surges without unnecessary tripping of the circuit.
• Breaking capacity: 6kA – a high value guaranteeing the safety of the installation in the event of a short circuit.
• Number of poles: 4P – allows protection of the entire circuit in one device.

BKN circuit breakers are a proven choice for professionals and demanding users who value the reliability and safety of electrical installations. Thanks to their solid construction and high technical parameters, they ensure long-lasting and trouble-free operation.
