Product Description

Frequently Asked Questions

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.

What are the differences between 2P, 3P, and 4P circuit breakers?

The 'P' stands for poles. A 2P breaker protects two live wires (single-phase), a 3P breaker protects three phase lines (three-phase systems), and a 4P breaker protects three phase lines plus the neutral line for enhanced circuit protection.

Where are OFNC Series Miniature Circuit Breakers suitable for use?

OFNC Series MCBs are suitable for industrial, commercial, and residential electrical distribution systems requiring reliable protection against overcurrents and electrical faults.

How do I choose the correct MCB rating for my equipment?

Select an MCB based on total load current, operating voltage, tripping characteristics (Curve B, C, or D), and the required breaking capacity for your specific application setup.

Can an MCB be reused after tripping?

Yes. Unlike standard electrical fuses, Miniature Circuit Breakers are reusable. Once the fault condition is cleared, the operating switch can simply be toggled back to the 'ON' position.
