## Summary description

The LSiS BKH 1P D63A is a single-pole miniature circuit breaker designed for reliable electrical circuit protection. It features a 63A rated current, 10kA breaking capacity, and operates on AC systems. This D-curve breaker is ideal for industrial and commercial applications requiring protection against overloads and short circuits, ensuring safety and stability in electrical distribution networks.

## Long description

The LSiS BKH 1P D63A is a high-performance single-pole miniature circuit breaker engineered to provide robust protection for electrical circuits. Designed for AC systems, this device offers a rated current of 63A and a substantial breaking capacity of 10kA, making it a reliable component for managing electrical distribution in demanding environments. Its D-curve characteristic ensures it can handle high inrush currents, providing effective defense against overloads and short circuits.
Advantages
This circuit breaker stands out due to its high breaking capacity of 10kA, which allows it to safely interrupt significant fault currents, thereby protecting downstream equipment and wiring from damage. The D-curve tripping characteristic is specifically optimized for loads with high starting currents, such as motors or transformers, preventing nuisance tripping during normal operation. Its compact single-pole design facilitates efficient use of space in distribution boards while maintaining high standards of safety and operational stability.
Suitable for
Industrial machinery and motor control circuits
Commercial electrical distribution panels
Systems with high inductive loads
Protection of lighting circuits with high inrush currents
When it may not be suitable
This device is not intended for use in DC electrical systems, as it is specifically designed for AC operation. Additionally, the D-curve characteristic may be less sensitive for standard residential lighting or general-purpose outlets compared to B or C curve breakers, potentially delaying protection for low-current faults.
Key specifications
Rated current: 63A
Number of poles: 1
Breaking capacity: 10kA
Tripping characteristic: D-curve
Operating voltage: AC
How to use
The circuit breaker should be installed by a qualified electrician into a standard DIN rail distribution board. Ensure that the supply power is disconnected before mounting the device. Secure the breaker onto the rail and connect the incoming line to the top terminal and the outgoing load wire to the bottom terminal, ensuring all connections are tightened to the manufacturer's specified torque to prevent overheating.
What to consider before purchase
Verify that the D-curve characteristic matches your specific load requirements
Ensure the 63A rating is appropriate for your circuit's total load
Confirm compatibility with your existing DIN rail enclosure
Check that the system voltage is compatible with AC-rated equipment
Usage recommendations
Regularly inspect the circuit breaker for signs of thermal damage or loose connections. It is recommended to perform a functional test periodically to ensure the mechanism remains responsive and provides reliable protection for your electrical infrastructure.
