Overcurrent circuit breaker, 6kA BKN series 1P 32A B characteristic BKN 1P B32A

Safety and Reliability in Your Installation

This single-pole circuit breaker from the BKN series, with a rated current of 32A, is a key element in protecting electrical circuits in residential and industrial buildings. Designed to work with 230/400V AC (and 48V DC per pole), it provides effective protection against overloads and short circuits. Its high short-circuit breaking capacity – up to 6kA – guarantees a quick response in emergency situations, minimizing the risk of damage and fire.

Manufactured in accordance with IEC/EN 60898-1 and IEC/EN 60947-2 standards, the BKN circuit breaker is characterized by high quality and durability. The B characteristic means that the breaker reacts quickly to current increases, but is also resistant to short-term load surges, which is particularly important when connecting devices with electric motors or other loads with high inrush current. This avoids unnecessary tripping of the circuit during normal operation of devices.

• Fast response: Short-circuit breaking capacity of 6kA ensures rapid intervention in the event of a failure.
• Versatility: Designed for use in both homes and industrial facilities.
• Durability: Withstands up to 20,000 mechanical cycles and 10,000 electrical cycles, translating to a long service life.
• Compliance with standards: Meets the requirements of IEC/EN 60898-1 and IEC/EN 60947-2 standards, guaranteeing safety.
• Compact size: 1 module width makes it easy to install in electrical panels.
• Overload and short circuit protection: Provides comprehensive protection for the electrical installation.

The BKN circuit breaker has a limitation class 3, which means it effectively limits the arc energy during a short circuit. The maximum backup fuse is 125A gG, allowing for the selection of appropriate preliminary protection for the installation. The IP20 degree of protection provides protection against accidental contact.
