Overcurrent circuit breaker, 6kA series BKN 2P 25A characteristic D BKN 2P D25A

Overcurrent circuit breakers of the BKN series – reliable protection of installations

The BKN 2P D25A overcurrent circuit breaker is an element used to protect electrical circuits against overloads and short circuits. Designed for both home and professional use, it ensures safety and durability of the installation. Characteristic D makes this circuit breaker particularly recommended for protecting circuits with receivers with high starting current, such as motors, transformers or heating devices.

Construction and application

The BKN 2P D25A circuit breaker is a two-pole device with a rated current of 25A and a breaking capacity of 6kA. This means that it is able to safely interrupt the circuit in the event of a short circuit with a value of up to 6000 amps. Characteristic D provides delayed tripping, which helps avoid unnecessary shutdowns caused by short-term current surges during device startup. Mounting is done on a TH35 rail (DIN rail), which facilitates integration with the existing switchgear.

Key features and benefits

• Characteristic D: ideal for protecting circuits with motors, transformers and other receivers with high starting current – allows for smooth device start-up without unnecessary shutdowns.
• Breaking capacity 6kA: ensures effective protection against the effects of short circuits, minimizing the risk of damage to the installation and equipment.
• Two-pole (2P): allows disconnection of both the phase and neutral conductors, providing complete isolation of the protected circuit.
• Mounting on TH35 rail: facilitates quick and easy installation in the switchgear – saves time during installation.
• Compliance with standards: LS Electric circuit breakers meet strict safety standards, guaranteeing reliable operation and long service life.
• Compact dimensions: allow installation in limited space – an ideal solution for tight switchgear.
