Overcurrent circuit breaker, 6kA BKN series 3P 4A B characteristic BKN 3P B4A

Electrical installation protection with BKN 3P B4A circuit breaker

BKN 3P 4A rated current circuit breaker is a reliable element protecting electrical installations against the effects of overloads and short circuits. Designed by LS Electric, this three-pole circuit breaker with characteristic B provides effective protection in both domestic and industrial installations.

Characteristics and application

The BKN 3P B4A circuit breaker is characterized by a type B tripping curve, which means it is ideal for protecting circuits with devices with high starting current, such as electric motors or transformers. The B curve allows for short-term exceeding of the rated current without unnecessary tripping, minimizing the risk of false alarms and downtime of devices. The three-pole design provides complete protection in three-phase circuits.

Advantages and benefits

• Effective protection: Protects the installation against overloads and short circuits, protecting electrical devices from damage.
• B curve: Ideal for circuits with devices with high starting current – motors, transformers, etc. Allows for momentary overloads without tripping the circuit.
• Three-pole design (3P): Provides complete protection in three-phase installations.
• Rated current 4A: Well suited for protecting circuits with lower power consumption.
• High reliability: A product of the renowned manufacturer LS Electric guarantees long-lasting and trouble-free operation.
• Easy installation: Standard dimensions and installation method facilitate installation in electrical switchboards.

Construction and parameters

The BKN 3P B4A circuit breaker has been designed with durability and safety in mind. Its compact design allows for easy placement in standard switchboards. The rated short-circuit breaking capacity is 6kA, which provides effective protection even in the event of serious disturbances in the electrical network. Made of high-quality materials resistant to environmental conditions, it ensures reliable operation for a long time. Thanks to this, both installers and end-users can be sure of the safety and stability of the electrical system.
