## Long description

The LSiS BKH 3P D125A is a high-performance 3-pole miniature circuit breaker engineered to provide robust electrical protection in demanding industrial and commercial environments. This device is designed to safeguard electrical circuits by effectively interrupting power in the event of overloads or short circuits, thereby preventing damage to equipment and infrastructure. With its compact 1.5-module design, it offers an efficient solution for modern electrical distribution systems where space optimization is essential.
Advantages
This miniature circuit breaker stands out due to its high breaking capacity of 10kA, which ensures reliable performance even under significant fault conditions. The 3-pole configuration allows for the simultaneous protection of three phases, making it highly suitable for three-phase electrical systems. Its durable construction and precise engineering contribute to long-term operational stability and safety, minimizing the risk of electrical fires or equipment failure. The compact 1.5-module footprint facilitates easier integration into standard distribution boards without compromising on power handling capabilities.
Suitable for
Industrial electrical distribution panels
Commercial building power systems
Three-phase motor protection
Main circuit protection in sub-distribution boards
This circuit breaker may not be suitable for residential applications where a lower amperage rating is required or where the specific 1.5-module width does not align with existing standard 1-module DIN rail configurations. It is also not intended for use in environments with extreme moisture or corrosive gases without appropriate protective enclosures.
Key specifications
Rated current: 125A
Number of poles: 3
Breaking capacity: 10kA
Module width: 1.5 modules
Tripping characteristic: D-curve
Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is mounted onto a standard DIN rail within a distribution board. Ensure that the supply cables are correctly sized for a 125A load and securely tightened to the terminals to prevent overheating. After installation, verify the connections and perform a functional test to ensure the breaker operates correctly within the circuit.
What to consider before purchase
Verify that the 125A rating matches your circuit load requirements
Ensure your distribution board has sufficient space for a 1.5-module wide device
Confirm that the D-curve tripping characteristic is appropriate for your specific load type
Check compatibility with existing busbar systems
For optimal safety and longevity, regularly inspect the terminal connections for tightness and ensure the device is kept free from dust and debris within the distribution enclosure.
