Frequently Asked Questions (FAQ)

What is a Miniature Circuit Breaker (MCB)?

A Miniature Circuit Breaker (MCB) is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current, typically resulting from an overload or short circuit.

What does the "C63" rating indicate in the OFIS-DS Series?

"C" refers to the tripping characteristic curve, suitable for medium inductive loads like commercial lights and small motors. "63" represents the rated current capacity of 63 Amperes.

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

2P breakers protect two single-phase lines or one phase and neutral; 3P breakers are used for three-phase systems without a neutral line; 4P breakers protect three-phase lines along with a neutral line.

Where are OFIS-DS Series MCBs typically applied?

They are suitable for residential, commercial, and industrial electrical distribution networks requiring reliable overcurrent and short-circuit protection.

How do I choose the correct pole count (2P, 3P, or 4P) for my project?

Selection depends on your power system wiring configuration. Single-phase applications generally use 2P, while three-phase power systems require 3P or 4P depending on neutral line protection requirements.
