Hi im looking for an MCB with the following specs please let me know if schneider offers one; standards IEC/EN 60898-1 The concept behind it evolved in the 1970s-80s when it was a single standard for all low-voltage switchgear. Two requirements that ensure reliability of circuit- breakers are the ultimate breaking capacity (I cu) and service breaking capacity (I cs ). I cu is the maximum short-circuit current that the circuit- breaker can break without damage which might be 6,000 A or 10,000 A and in the case of MCCBs, 200,000 A for specific voltage ratings. Maximum earth fault loop impedance (Zs) values are tabulated in BS 7671 for cbs to BS EN 60898-1 but the maximum Zs values for cbs to BS EN 60947-2 need to be obtained from the manufacturer.

Hi im looking for an MCB with the following specs please let me know if schneider offers one; standards IEC/EN 60898-1 The concept behind it evolved in the 1970s-80s when it was a single standard for all low-voltage switchgear. Two requirements that ensure reliability of circuit- breakers are the ultimate breaking capacity (I cu) and service breaking capacity (I cs ). I cu is the maximum short-circuit current that the circuit- breaker can break without damage which might be 6,000 A or 10,000 A and in the case of MCCBs, 200,000 A for specific voltage ratings. Maximum earth fault loop impedance (Zs) values are tabulated in BS 7671 for cbs to BS EN 60898-1 but the maximum Zs values for cbs to BS EN 60947-2 need to be obtained from the manufacturer.
