Miniature circuit breakers FAQs
A miniature circuit breaker (MCB) is an automatic electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. It automatically switches off the electrical circuit when it detects a fault.
MCBs are used for lower capacity needs and provide protection against overload and short circuit for small electrical circuits. Air circuit breakers (ACBs) are used in higher capacity commercial and industrial applications and can handle larger electrical loads and they use air as the arc extinguishing medium.
Yes we do!
To choose the right MCB, consider the following key factors:
- Load Assessment: Determine the typical operating current and select an MCB with an appropriate current rating to avoid unnecessary tripping.
- Load Type: Match the MCB to the load type—motors, lights, etc.—requiring specific tripping characteristics (B, C, D, K, Z curves).
- Breaking Capacity: Ensure the MCB can handle the maximum expected fault current safely.
- Voltage Compatibility: Verify that the MCB's voltage rating matches your system’s voltage.
- Compliance: Choose MCBs that meet relevant safety and quality standards.
