Merlin Gerin model NSD EZC MCCB/moulded case circuit breaker
The NSD series plastic outer covering type circuit breaker is suitable in exchanges 50/60Hz, the fixed working voltage is highest to 550V, nominal current In the 15-630A low pressure electrical power distribution system uses in protecting the distribution line and the current collector, exempts is overloaded, the short circuit and the earth fault harm, provides the power supply the continuity and the reliability.
Product performance characteristic description :
1, 15~630A, 5 plants the shell electric current rank
2, Compact NSD and EasyPact NSD are 3 extremely stationary types
3, Compact NSD biggest 36kA? K/The F two kind of minutes break ability
4, EasyPact NSD biggest 50kA? E/The M two kind of minutes break ability
5, Below 250A is thermomagnetism trip, the 400/630A distributor rotor trip, provides the overload
6, VigiCompact the NSD highest electric current specification to the 250A, 3/4 stationary type,
7, The trip with reports to the police does not trip two kind of functions
8, Leakage protection movement threshold value 100, 300, 500 mA 33 adjustable, operating time 200mS fixed not adjustable.
