OEM OF10KA Series 2P Miniature Circuit Breaker Factories, Manufacturer

The OF10KA Series 2P (Double-Pole) miniature circuit breaker is a high-performance, full-pole protective device engineered for single-phase AC distribution systems. Its core design incorporates a mechanically linked mechanism to achieve synchronized interruption of both the line (L) and neutral (N) conductors. It provides precise overload and short-circuit protection while ensuring complete electrical isolation of the circuit. This product is particularly suitable for applications with explicit requirements for operational safety and fault isolation integrity, effectively eliminating potential hazards associated with a live neutral conductor.

Product Description

Frequently Asked Questions

What does 10KA breaking capacity mean in miniature circuit breakers?

A 10kA (kilo-amperes) breaking capacity indicates the maximum fault current that the miniature circuit breaker (MCB) can safely interrupt without causing damage or risk to the electrical installation.

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

1P (Single Pole) protects a single phase line for standard 230V circuits. 3P (Three Pole) protects three phase lines for 400V industrial systems. 4P (Four Pole) protects three phase lines along with the neutral line for complete electrical isolation.

Where are OF10KA series miniature circuit breakers typically applied?

The OF10KA series circuit breakers are designed for commercial distribution panels, industrial control systems, and residential installations requiring reliable overload and short-circuit protection.

How does an MCB protect electrical systems against damage?

MCBs provide dual-trip protection: thermal tripping mechanism for persistent overload conditions and electro-magnetic tripping mechanism for immediate short-circuit fault currents.

Why choose a 10kA rated breaker over a standard 6kA breaker?

10kA circuit breakers provide a higher safety threshold, making them essential for installations located near power transformers or in industrial setups where potential fault currents are higher.
