Residual Current Circuit Breaker RCCB (KNL1-100) 80A, 100A 30mA, 300mA 2p/4p Magnetic
Inquire NowDescription
KNL1 Series Residual Current Circuit Breaker (RCCB) is designed to protect against electrical shocks and prevent accidents caused by current leakage. Suitable for both industrial and commercial applications, this RCCB operates at a rated current of up to 100A and is compatible with circuits operating at 240V (2-pole) or 415V (4-pole) at frequencies of 50/60Hz. When a leakage current exceeds the predetermined limits, the device quickly disconnects the power supply, ensuring user safety.
This model adheres to the IEC/EN61008.1 and GB16916.1 standards, ensuring reliable performance. Utilizing a zero-sequence current transformer, the RCCB continuously monitors the current and activates the electromagnetic tripper to break the circuit when leakage is detected, thus providing effective protection against electrical hazards.
