LSiS BKH 4P C100A Miniature Circuit Breaker, 10kA, 4-Pole, 100A, C-Curve

The LSiS BKH 4P C100A is a robust 4-pole miniature circuit breaker engineered to provide dependable protection for electrical distribution systems. Designed for high-performance environments, this device effectively monitors electrical circuits to prevent damage from overloads and short circuits, ensuring the integrity of your infrastructure. With its 100A rated current and 10kA breaking capacity, it serves as a critical component in maintaining operational safety and reliability in demanding electrical setups.

Advantages

This miniature circuit breaker offers exceptional durability and consistent performance under varying load conditions. Its C-curve tripping characteristic provides a balanced response, making it highly versatile for a wide range of industrial and commercial electrical installations. The 4-pole configuration allows for comprehensive control and protection of three-phase systems with a neutral line, simplifying the design of complex distribution boards while maintaining high safety standards.

Suitable for

• Industrial electrical distribution panels
• Commercial building power management systems
• Three-phase motor protection
• Large-scale lighting and heating circuits

When it may not be suitable

This device is not intended for residential applications where the current requirements are significantly lower than 100A, as it may not provide the necessary sensitivity for smaller household appliances. It is also not suitable for DC power systems unless specifically rated for such use by the manufacturer.

Key specifications

• Rated current: 100A
• Number of poles: 4
• Breaking capacity: 10kA
• Tripping characteristic: C-curve

How to use

The LSiS BKH 4P C100A 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 circuit's total load requirements.
• Ensure the distribution board has sufficient space for a 4-pole device.
• Confirm that the C-curve characteristic is appropriate for your specific load types, such as motors or inductive equipment.

Usage recommendations

Always perform a thorough inspection of the electrical system before installation. Ensure that all connections are tightened to the manufacturer's specified torque settings to maintain optimal contact and prevent electrical arcing.
