F462 F464 series Residual current breaker (without over-current protection) issuitable for the line of AC 50/60Hz,voltage 240V(2pole)/415V(4pole),rated currentup to 63A.When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will cut off the power rapidly to protecthuman safety and prevent the accident due to the current leakage.It can beused as infrequent changeover of the line in normal situation. It is applicable toindustrial site, commercial site, tall building and civil house.It complies with standard of IEC/EN61008.1 and GB16916.1
BASIC SPECIFICATION AND MAIN PARAMETERS Frame class 63A Rated working voltage 240/415V Rated frequency 50/60Hz Rated working current 16, 25, 40, 63A Rated residual operating current 0.03, 0.1, 0.3, 0.5A Rated residual un-operating current 0.015, 0.05, 0.15, 0.25A Sensibility A &AC Type Maximum operating time IΔn t≤0.1s, 5IΔn t≤0.04s Rated making and breaking capacity In≤50A 500A, In≤63A 630A Limiting value of un-operating current 6In Rated limiting short-circuit current 3000A Pole number 2P, 4P Mechanical life 20000 Electric life 4000
