KNL1-100 Residual Current Circuit Breaker
Inquire NowDescription
The KNL1-100 Residual Current Circuit Breaker (RCCB) is an essential safety device designed to protect against electric shock and prevent electrical accidents caused by current leakage. It operates on AC 50/60Hz and supports voltages of 240V (2 pole) and 415V (4 pole), with a rated current capacity of up to 100A. Instantly disconnecting power when it detects a fault condition, this RCCB ensures human safety by rapidly cutting off electricity in the event of a leakage current. It is suitable for various applications, including industrial sites, commercial buildings, high-rise structures, and residential homes. The KNL1-100 complies with the GB 16916.1 and IEC/EN 61008.1 standards, guaranteeing reliability and safety in its operation.

Additional Information
The KNL1-100 RCCB features a zero-sequence current transformer for monitoring the conductor phases. Under normal conditions, the transformer maintains a zero output voltage. However, if a leakage current occurs, the transformer activates the electromagnetic trip mechanism, disconnecting the power supply and ensuring safety. This innovative design enhances the reliability of the device in protecting against electrical hazards.
