Overcurrent circuit breaker, 6kA series BKN 3P 63A characteristic D BKN 3P D63A

Installation protection with D characteristic

A three-pole BKN series circuit breaker with a rated current of 63A is a reliable safety element in electrical installations. Designed to protect circuits exposed to high surge currents and overloads, it performs particularly well in applications with devices with high power consumption during start-up. The D characteristic provides a delayed tripping time of the circuit breaker, which minimizes the risk of unnecessary tripping of the circuit during short-term current surges.

Application and design features

The BKN 3P D63A circuit breaker is designed to protect circuits in residential, commercial and industrial buildings. Its three-pole construction provides comprehensive protection against short circuits and overloads in all phases. The rated current of 63A allows for the protection of circuits powering devices with significant power consumption, such as electric heaters, stoves, motors or pumps. The breaking capacity of 6kA guarantees effective disconnection of the circuit in the event of a short circuit, protecting the installation and devices from damage.

• D characteristic: Delayed tripping time of the circuit breaker allows for smooth start-up of devices generating high surge currents – e.g. electric motors or heating devices.
• Three-pole construction (3P): Provides full protection of all phases in a three-phase installation.
• Rated current 63A: Enables protection of circuits with high power consumption.
• Breaking capacity 6kA: Guarantees effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage.
• Wide range of applications: Ideal for protecting circuits in residential, commercial and industrial buildings.

BKN circuit breakers are a proven proposition for installers looking for reliable and effective solutions in the field of overvoltage and short-circuit protection. Their solid construction and high quality workmanship ensure long-lasting and trouble-free operation.
