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
