Overcurrent circuit breaker, 10kA BKH series 1P 80A characteristic D BKH 1P D80A

Overcurrent switch – reliable protection of electrical installation

This single-pole overcurrent switch of the BKH series with a rated current of 80A is a key protective element in every electrical installation. Designed to protect against the effects of overloads and short circuits, it ensures safety in both domestic and industrial applications. Characteristic D makes it particularly resistant to sudden current surges, making it an ideal choice for circuits powering devices with high inrush current, such as motors or transformers.

Construction and application

The BKH 80A/1P switch is a modular device designed for mounting on a TH35 rail. Its compact dimensions make installation easy even in limited space. The use of characteristic D means a delayed response to current increase, which avoids unnecessary tripping during short-term overloads. This makes the switch perfect for protecting circuits powering receivers generating high inrush currents.

Key features and benefits

• High breaking capacity: The breaking capacity of short-circuit current at 10kA guarantees effective protection of the installation in the event of a serious failure.
• Characteristic D: Provides a delayed response to short-term overloads, minimizing the risk of false alarms and unnecessary power interruption. This is especially important when powering devices with high starting current.
• Modular construction: Allows easy mounting on a TH35 rail and flexible adaptation to the needs of a specific installation.
• Wide range of applications: Ideal for protecting lighting, socket and electrical appliance circuits in residential, commercial and industrial buildings.
• Solid construction: Made of high-quality materials, which ensures long-lasting and reliable operation.
• Protection against overload and short circuit: Protects the circuit against damage caused by overloads and short circuits – like any standard overcurrent switch.

The BKH 1P D80A switch is an investment in the safety and reliability of your electrical installation. Its solid construction and high technical parameters guarantee long-term protection against the effects of electrical failures.
