 Scope of application

         RM1 Series moulded case circuit breaker(hereinafter referred to as RM1) is one of our company new type circuit breakers which is adopted international advanced design and manufacture technic to develop by ourselves. And its rated insulated voltage is 800V(RM1－63is 500V), applied to AC 50HZ(60Hz), rated voltage 690V(RM1－63is 400V), direct current 250V or less, rated working current 10A up to 1250A. it used in switching the circuitry and starting electromotor unfrequent. RM1 have overload, short-circuit and lack voltage protection, protecting circuitry and power equipment without damage.
        RM1 according to rated limit short-circuit breaking capability (Icu): Type L (standard), Type M (High-breaking Type), Hstyle (High-breaking Type). They have many characteristic of reasonable structure, small volume, high breaking capability, short fly arc distance (parts of specification no fly arc), vibration resist etc. It’s suitable in ship or land.
         This circuit breaker can be upright installation and level installation.
         This circuit breaker product accord to Standard as follows :
