## Long description

The LSiS BKH 1P D100A is a high-performance miniature circuit breaker engineered to provide reliable protection for electrical circuits in demanding environments. This single-pole device is designed to handle a rated current of 100A and offers a robust breaking capacity of 10kA, ensuring safety against short-circuits and overloads. With its D-type tripping characteristic, it is specifically suited for circuits with high inrush currents, while its compact 1.5-module width allows for efficient space utilization within electrical distribution boards.
Advantages
This circuit breaker stands out due to its high breaking capacity, which provides superior protection in industrial and commercial settings. The D-type tripping curve makes it highly effective for managing equipment that experiences significant current spikes during startup, such as large motors or transformers. Its compact design helps save valuable space in switchgear, and the high-quality construction ensures long-term operational reliability and safety for electrical installations.
Suitable for
Industrial power distribution systems
Commercial building electrical panels
Protection of circuits with high inrush currents
Large motor and transformer installations
When it may not be suitable
This device is not intended for residential lighting or standard household outlet circuits, as the D-type tripping characteristic is specifically calibrated for high-surge loads. Using it in applications with low inrush currents may result in delayed protection during a fault condition.
Key specifications
Rated current: 100A
Breaking capacity: 10kA
Number of poles: 1P
Tripping characteristic: D-type
Width: 1.5 modules
How to use
The LSiS BKH 1P D100A should be installed by a qualified electrician onto a standard DIN rail within a distribution board. Ensure that the supply cables are correctly sized for a 100A load and securely fastened to the terminals to prevent overheating. Once mounted, the device can be manually switched on or off using the front toggle lever, which also indicates the status of the circuit.
What to consider before purchase
Verify that the 1.5-module width fits your existing distribution board layout.
Ensure the D-type characteristic matches the requirements of your connected equipment.
Confirm that the 100A rating is appropriate for your circuit load.
Check that the 10kA breaking capacity meets local safety regulations for your installation site.
Usage recommendations
Always ensure the power supply is disconnected before attempting installation or maintenance. Regularly inspect the terminals for tightness and check for any signs of thermal discoloration to maintain optimal performance.
