Product Description

Frequently Asked Questions

Q: What is an OFL8 Series Miniature Circuit Breaker (MCB)?

An OFL8 Series MCB is an automatically operated electrical switch designed to protect low-voltage electrical circuits from damage caused by excess current, overload, or short circuits.

Q: What is the difference between 2P, 3P, and 4P Miniature Circuit Breakers?

The number before "P" indicates the number of poles (protected lines). 2P switches two lines (typically single-phase or line-to-line), 3P switches three phase lines, and 4P switches three phase lines along with the neutral line for complete circuit isolation.

Q: How do I choose the correct MCB pole rating for my application?

Selection depends on your power system. Use 2P for single-phase systems requiring neutral isolation, 3P for standard 3-phase industrial equipment without neutral, and 4P for 3-phase 4-wire distribution networks.

Q: Are these miniature circuit breakers suitable for commercial and residential installation?

Yes, OFL8 Series MCBs are engineered for versatile deployment across residential distribution boards, commercial office buildings, and industrial electrical control setups.

Q: What protective functions do OFL8 series circuit breakers offer?

They offer dual-protection mechanisms: a thermal tripping mechanism for delayed overload protection and an electromagnetic tripping mechanism for instantaneous short-circuit protection.
