LSiS BKH 3P D100A Miniature Circuit Breaker 10kA 1.5 Module

The LSiS BKH 3P D100A is a high-performance miniature circuit breaker engineered to provide robust protection for electrical circuits in demanding environments. This 3-pole device is designed to handle a rated current of 100A and features a significant breaking capacity of 10kA, ensuring safety during electrical faults. Its specialized 1.5-module width allows for optimized space management within standard electrical distribution boards, making it a practical choice for modern power systems.

Advantages

This circuit breaker offers exceptional reliability through its advanced internal mechanism, which ensures consistent performance under various load conditions. The compact 1.5-module design is particularly beneficial for installations where panel space is limited, allowing for higher density of protection devices without compromising safety. With its high breaking capacity, it effectively mitigates the risks associated with short circuits and overloads, providing long-term stability for industrial and commercial electrical infrastructure.

Suitable for

• Industrial power distribution systems
• Commercial building electrical panels
• Protection of high-current machinery
• General electrical circuit safety in professional installations

When it may not be suitable

This device is not intended for residential applications where lower current ratings are typically required. It is also not suitable for environments with extreme moisture or corrosive gases unless housed in an appropriately rated protective enclosure.

Key specifications

• Number of poles: 3
• Rated current: 100A
• Breaking capacity: 10kA
• Module width: 1.5 modules
• Tripping characteristic: D-curve

How to use

The LSiS BKH 3P 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 installed, the device can be manually toggled to the ON position to energize the circuit. In the event of a fault, the breaker will automatically trip to the OFF position, requiring a manual reset after the underlying issue has been resolved.

What to consider before purchase

• Verify that the 100A rating matches your specific load requirements
• Ensure the 1.5-module width is compatible with your existing distribution board layout
• Confirm that the D-curve tripping characteristic is appropriate for your equipment
• Check that the installation environment meets the necessary safety standards

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 operational safety.
