Automatic Circuit Breaker Retrofit Replacement Module for Electrical Upgrades

Block replacement circuit breaker (retrofit )are designed to upgrade the input and output blocks of electrical energy in the existing NKU voltage up to 690 V AC frequency 50 or 60 Hz, to conduct current in normal mode, infrequent operational switching on and off (the number is specified in the operating manual for a particular AV from the delivery set) of the specified circuits and protection of electrical equipment from overloads and short circuits. BZAV is a mounting base on which a new AB with contact leads-adapters is installed. The mounting base ensures mating with the mounting holes of the circuit breaker to be replaced. The contact leads-adapters ensure precise mating of the new circuit breaker leads with the busbars for connection of the replaced AB
