Frequently Asked Questions

Q What is a Miniature Circuit Breaker (MCB)?

A Miniature Circuit Breaker (MCB) is an automatically operated electrical switch designed to protect low-voltage electrical circuits from damage caused by overload or short circuits.

Q What is the difference between 2P, 3P, and 4P MCBs?

The number of poles (P) determines the number of lines protected. A 2P MCB switches two lines, a 3P MCB switches three lines for three-phase systems, and a 4P MCB provides protection across three phase lines plus the neutral line.

Q How do I choose the correct pole count for my system?

Select a 2P circuit breaker for single-phase systems requiring neutral protection, 3P for standard three-phase industrial loads, and 4P when full system neutral isolation is needed.

Q What safety mechanisms are built into these circuit breakers?

These MCBs feature thermal-magnetic tripping mechanisms for fast current interruption, robust flame-retardant housings, and clear contact position indications for operational safety.

Q Are these MCBs compatible with standard distribution boards?

Yes, all multi-pole miniature circuit breakers are designed for standard DIN-rail mounting, making them suitable for residential, commercial, and industrial power distribution units.
