LSiS BKH 2P D125A Miniature Circuit Breaker, 2-Pole, D-Curve, 125A, 10kA

The LSiS BKH 2P D125A is a robust 2-pole miniature circuit breaker engineered to provide dependable protection for electrical systems. Designed to handle high-current applications, this device effectively safeguards circuits against overloads and short circuits. With its D-curve tripping characteristic, it is specifically optimized for loads with high inrush currents, ensuring stable operation in demanding electrical environments.

Advantages

This circuit breaker offers exceptional reliability and durability in industrial and commercial settings. Its 10kA breaking capacity ensures that it can safely interrupt high fault currents, preventing damage to downstream equipment and wiring. The 2-pole configuration allows for the simultaneous disconnection of both live conductors, providing enhanced safety during maintenance or fault conditions. The compact design facilitates efficient installation in standard distribution boards, making it a versatile choice for professional electrical installations.

Suitable for

• Industrial machinery and motor control circuits
• Commercial electrical distribution panels
• Systems with high inductive loads
• Protection of lighting circuits with high inrush current

This device may not be suitable for residential applications where lower current ratings are required or where the D-curve tripping characteristic is too insensitive for standard household appliances. It is specifically designed for high-load industrial environments and should not be used in systems exceeding its rated voltage or breaking capacity.

Key specifications

• Number of poles: 2
• Rated current: 125A
• Tripping characteristic: D-curve
• Breaking capacity: 10kA
• System type: AC

Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is mounted onto a standard DIN rail within an enclosure. Ensure that the supply cables are properly sized for a 125A load and that all terminal connections are tightened to the manufacturer's specified torque to prevent overheating.

What to consider before purchase

• Verify that the 125A rating matches your circuit load requirements
• Ensure the D-curve characteristic is appropriate for your specific equipment
• Check available space in your distribution board for a 2-pole module
• Confirm compatibility with your existing AC electrical system

For optimal performance and safety, regularly inspect the circuit breaker for signs of thermal stress or physical damage and ensure that the electrical load does not consistently exceed the rated current capacity.
