Nader Circuit Breaker

1. Rated voltage Rated voltage refers to the voltage level that the high-voltage circuit breaker can withstand during normal operation, and it determines the insulation level of the circuit breaker. The rated voltage (UN) refers to its line voltage. The rated voltage levels of commonly used circuit b...

Section Overview First, the definition of low-voltage circuit breakers, and perform standard classifications (a) is defined using a low voltage circuit breaker for low voltage power [AC (50Hz or 60Hz rated voltage and below 120, and the DC rated voltage of 1200v .] below the electrical power distribu...

Circuit Breakers commonly known as automatic air switch. Low voltage distribution network is one of the main switching device, the low pressure switch is a switch best performance. It can be used to turn on, breaking the normal load current, and has a function of automatic protection circuit. When th...

Formed into universal type (frame type) and a type molded case (device type) of two kinds of low voltage circuit breaker according to the structure. Breaker its structure is compact, reliable, safe, etc., in all types of building construction site as electrical distribution systems, cables, motors an...

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 ...
