China OF6KA Series 2P Miniature Circuit Breaker Factory, Manufacturer

The OF6KA Series double-pole (2P) miniature circuit breaker is a full-pole protection device specifically engineered for single-phase AC distribution systems. Its core design features a synchronized double-pole interruption mechanism, capable of simultaneously disconnecting both the line (L) and neutral (N) conductors. In addition to providing overload and short-circuit protection, it ensures complete electrical isolation of the circuit. This product is suitable for applications with explicit requirements for electrical safety isolation, effectively mitigating potential hazards caused by abnormal neutral conductor potential, thereby offering a higher level of security for the power distribution system.

Product Description

Frequently Asked Questions

What is the main function of the OF6KA Series Miniature Circuit Breaker?

The OF6KA Series Miniature Circuit Breaker (MCB) is designed to protect electrical circuits from damage caused by excess current, overload, or short circuits, automatically cutting off power when a fault is detected.

What is the difference between 1P, 3P, and 4-Pole circuit breakers?

A 1P (Single Pole) circuit breaker protects a single live phase line. A 3P (Three Pole) model protects three-phase power lines, while a 4-Pole model protects three live phase lines along with the neutral line for comprehensive circuit isolation.

Are OF6KA Series MCBs compatible with standard DIN-rail mounting?

Yes, OF6KA Series circuit breakers feature a standard modular construction designed for effortless snap-on mounting on standard 35mm DIN rails in distribution boards.

How do I choose the correct pole type for my application?

Select 1P for single-phase residential or small appliance circuits, 3P for heavy three-phase industrial machinery, and 4-Pole when complete neutral isolation is required for safety compliance.

What applications are these circuit breakers suitable for?

They are ideal for residential power distribution, commercial buildings, and industrial facility control panels requiring dependable circuit protection up to 6kA breaking capacity.
