Korlen Residual Current Circuit Breaker RCCB Knl1-63 (F360 Series) with Ce CB 3ka16A 25A 3
Inquire NowDescription
KNL1 Series Residual Current Circuit Breaker (RCCB) is designed to provide exceptional protection against electrical shocks and leakage currents. This circuit breaker operates at a frequency of 50/60Hz and supports voltages of 240V (2-pole) and 415V (4-pole), with a rated current capacity of up to 63A. It swiftly disconnects power to ensure human safety in the event of a current leakage, making it ideal for industrial sites, commercial buildings, tall structures, and residential homes. The device is compliant with IEC/EN61008.1 and GB16916.1 standards, ensuring reliability and safety in various applications.
Each phase of the conductor passes through a zero-sequence current transformer, which interacts with an electromagnetic tripper. Under normal conditions, the vector sum of each phase’s current is zero, ensuring safety. However, if leakage current rises, the system activates the electromagnetic release to break the power connection, effectively providing leakage protection.
