Overcurrent circuit breaker, 6kA series BKN 2P 63A characteristic D BKN 2P D63A

Overcurrent circuit breakers BKN series – protection of installations and devices

This two-pole BKN 2P 63A overcurrent circuit breaker with characteristic D is a protective element that will find application in both home and industrial installations. It provides effective protection against overloads and short circuits, protecting wires and connected devices. Characteristic D means that this circuit breaker is designed for circuits with high inrush currents, such as electric motors or transformers – it allows for short-term exceeding of the nominal current without unnecessary tripping.

Construction and application

The BKN 2P D63A circuit breaker is a modular device, mounted on a TH35 rail. Its two-pole construction means that it protects two independent circuits. It is intended for use in circuits with a voltage of 400V AC. The use of characteristic D makes it particularly recommended for protecting circuits with inductive loads that generate high starting currents. This minimizes the risk of false tripping caused by momentary load surges.

Key features and benefits

• Characteristic D: Provides a delayed response to short-term overloads, which is important when operating devices with motors or transformers.
• Rated current 63A: Allows for protection of circuits with higher power consumption.
• Breaking capacity 6kA: Guarantees safe interruption of a short circuit, minimizing the risk of damage to the installation and devices.
• Modular design: Enables easy mounting on a TH35 rail and flexible expansion of the switchboard.
• Two-pole protection: Protects two independent circuits in one device.
• Wide application: It will work in home installations, commercial buildings and industrial facilities.
• High reliability: Made of high-quality materials ensures long-lasting and trouble-free operation.
