Miniature Circuit Breakers (MCBs) (12 Products)
Miniature Circuit Breakers (MCBs) for Electrical Safety
Miniature Circuit Breakers (MCBs) are essential safety devices used by electricians and facility managers to protect electrical circuits from overcurrent and short circuits. These compact units automatically interrupt power flow when a fault is detected, preventing potential damage to appliances and wiring systems.
Available MCB Range
- Single-pole and multi-pole configurations
- AC and DC circuit breaker variants
- Various trip curves including B, C, and D
- Amperage ratings from 4 Amp up to 125 Amp
Choosing the Right MCB
Selecting the correct MCB requires matching the breaker's current rating to the circuit load and ensuring the trip curve aligns with the specific application requirements. Consider the pole count based on whether you are protecting a single-phase or three-phase supply. The breaking capacity, measured in kA, should also be evaluated to ensure it meets the prospective fault current of your installation.
