Overcurrent circuit breaker, 6kA BKN series 4P 40A characteristic D BKN 4P D40A

Protection of installations and devices – overcurrent circuit breaker series BKN

This four-pole overcurrent circuit breaker with D characteristic is a reliable protection for your electrical installation. Designed to protect circuits exposed to high surge currents, it is perfect for places where devices generating high starting loads are connected, such as motors or transformers. It provides effective protection against overload and short circuit, minimizing the risk of damage and fire.

Construction and application

The BKN 4P D40A circuit breaker is designed for mounting on a TH35 rail. Its compact dimensions allow for easy installation even in limited space. The D characteristic means a delayed response to current increase, which avoids unnecessary tripping during short-term load peaks – typical for devices with induction motors. This is an ideal solution for both home and industrial installations where stable power supply is crucial.

• Four-pole design: allows you to protect the entire circuit in one device.
• Rated current 40A: provides adequate protection for circuits with high power demand.
• Breaking capacity 6kA: guarantees safe interruption of a short circuit, protecting both the installation and people.
• D characteristic: provides resistance to short-term overloads, ideal for devices with motors or transformers.
• Mounting on TH35 rail: facilitates and speeds up installation.

By choosing this circuit breaker, you are investing in the safety and reliability of your electrical installation. It is a solid solution that will provide peace of mind for both you and your customers.
