Nader Circuit Breaker

Short-circuit breaker breaking capacity ≥ lines prospective short circuit current. Suppose a power supply (SL7 10 / 0.4kV transformer) capacity of 1600kVA, the secondary current of 2312A, short-circuit current which is at the outlet end of 5m 42.96kA. Is a rated current branch 125A, since this leg ...

The characteristics of circuit breakers mainly include: rated voltage Ue; rated current In; overload protection (Ir or Irth) and short-circuit protection (Im) trip current setting range; rated short-circuit breaking current (industrial circuit breaker Icu; household circuit breaker Icn) )Wait. Rated ...

What is a molded case circuit breaker? Molded case circuit breakers are generally suitable for the interface between the 400V power supply of the power supply system and the low-voltage power distribution system. They are widely used in the secondary load small power distribution box and the tertiary...

Circuit breakers are classified into universal type and plastic case type according to their structure. Among them, molded case circuit breakers are suitable for power distribution systems with rated voltage 690V, frequency 50/60Hz, and rated current 16 to 1600A or as protection equipment for transfo...
