4.5KA 6KA Miniature Circuit Breaker 1 Pole 2 Pole 3 Pole 4 Pole
1~63A MCB CURVE:B,C,D
KRIPAL has the design patent for these items
Description:
UKB1 series MCB is an automatically operated electrical switch
designed to protect an electrical circuit from damage caused by
overload or short circuit. Its basic function is to detect a fault
condition and interrupt current flow. Unlike afuse, which operates
once and then must be replaced, a circuit breaker can be reset
(either manually or automatically) to resume normal operation.
Circuit breakers are made in varying sizes, from small devices that
protect an individual household appliance up to large switchgear
designed to protect high voltage circuits feeding an entire city.
Features:
1. Protection against both overload and short circuit
2. High short-circuit capacity
3. Contact position indication
4. Applicable to terminal and pin/fork type busbar connection
5. Easy mounting onto 25&below mm DIN rail
