Overcurrent circuit breaker, 6kA series BKN 3P 3A characteristic B BKN 3P B3A

Protection of installations and devices – circuit breaker BKN 3P B3A

This three-pole BKN 3P B3A overcurrent circuit breaker is a reliable safety element for protecting electrical installations against overloads and short circuits. Designed to work with circuits with a rated current of 3A, it provides effective protection in both home and commercial installations. The B characteristic makes this circuit breaker particularly well suited for protecting circuits with receivers with moderate inrush current.

Construction and application

The BKN 3P B3A circuit breaker belongs to the BKN series, valued for its solid construction and reliable operation. Its construction based on a thermal-magnetic mechanism guarantees a quick reaction in the event of a dangerous situation. The three-pole design allows for the protection of the entire circuit, including the neutral conductor (depending on the configuration of the installation). These types of circuit breakers are used to protect:

• Lighting
• Socket outlets
• Distribution circuits
• Electrical devices with moderate inrush current

Parameters and characteristic features

The BKN 3P B3A circuit breaker is distinguished by several key parameters:

• Rated current (In): 3A – adapted to protect circuits with relatively low current consumption.
• Tripping characteristic: B – provides a quick response to overloads and short circuits, while tolerating short-term current surges during device start-up. This is important when protecting, for example, electric motors or transformers.
• Rated voltage (Ue): 415V AC – allows use in a wide range of electrical installations.
• Breaking capacity (Icn): 6kA – guarantees safe circuit interruption in the event of a short circuit with high current.
• Number of poles: 3P – provides full protection of a three-phase electrical circuit.
• Type of release: Thermal-magnetic - a combination of two mechanisms providing comprehensive protection against various types of failures.

This circuit breaker complies with EN/IEC 60898-1 and IEC60947-2 standards, which confirms its safety and quality. Thanks to this, you can be sure that it meets all the required standards and will provide effective protection for your electrical installation.
