Product Description

Frequently Asked Questions

What is the main function of an OFDL Series Miniature Circuit Breaker?

The OFDL series miniature circuit breaker is designed to automatically trip and break the electrical circuit during overload or short-circuit situations, protecting equipment and wiring from thermal damage and fire hazards.

What is the difference between 2P, 3P, and 4P circuit breakers?

2P circuit breakers protect two live conductors (or single-phase line + neutral). 3P breakers are built for three-phase systems without neutral protection, whereas 4P circuit breakers provide full protection for all three phase lines plus the neutral line.

How do I select the right breaker for my setup?

Selection depends on the system voltage, maximum current load, and phase requirements (2P, 3P, or 4P). Ensure the rated current and breaking capacity meet your panel’s safety specs.

Where are these miniature circuit breakers typically applied?

They are suitable for residential distribution boxes, commercial infrastructure, and industrial switchboards requiring reliable low-voltage electrical protection.

What should be done if the miniature circuit breaker trips?

Identify and resolve the underlying issue causing the overload or short circuit first. Once the fault is cleared, manually toggle the breaker lever back to the ON position.
