- Type C curve means it trips at 5 to 10 times the rated current of 4A
- High breaking capacity of 10kA for maximum protection
- 400V-rated AC voltage for low-voltage applications
- Broad operating temperature range of -25В°C to +55В°C
How does an MCB work?
A miniature circuit breaker contains a bi-metallic strip. When an overcurrent passes through, this strip is heated and bends, causing it to release a latch which in turn breaks the circuit.
