L7 series mini circuit breaker

L7 series mini circuit breaker
Product Detailed
shortage and overload, in lighting distribution system in industry, commerce and dwelling, can protect fractional electric motor

L7 series min circuit breaker

APPLICATIONS

The products of L7 belong to the advanced level of the nineties in the world instead of the older generation of L7. 

They have protection function as in shortage and overload, and are used in lighting distribution system in industry, 

commerce and dwelling, and can protect fractional electric motors.

And they also have many merits of high protective grad(up to IP20), high break capacity, reliable sensitive action, convenient, multi-pole assembling, long life etc. They are mainly adapted to the circuit of AC 50Hz, 240V in single pole, 415V in double, 

three, four poles for protecting overload and short circuit. Meanwhile, they are also used in turning on or off the 

electric apparatus and lighting circuit under the normal condition.
