Manufacturers may also provide maximum Zs values for their MCBs and RCBOS which are for conductor operating temperatures of 70o C. These values of Zs are higher than in Table 41.3 of BS 7671, as they are based on the actual operating characteristics of their own MCBs. MCB is a miniature circuit breaker and MCCB is a molded case circuit breaker. What is the difference between short circuit values mentioned in the 2 standards , Icn values in IEC60898 & Icu value in IEC60947. Infrequent switching of cbs on load is admissible for the purposes of isolation or emergency switching. I can say is that mix-ups of standards happen. Icu 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. The two major components of the trip curve are: With lower overload currents, only the thermal trip is active. Testing a 4mm radial circuit today or so I Hi i am trying to figure out if there is any requirement for ip ratings for sockets in a shed.
