OEM OFGX 2P63A High-Performance Miniature Circuit Breaker Factories, Factory

The OFGX 2P63A is a high-performance two-pole (2P) miniature circuit breaker specifically designed for the final circuits of low-voltage power distribution systems. This product utilizes a high flame-retardant, high-strength engineering plastic housing, integrating a sophisticated dual-protection mechanism for overload and short circuits. It is designed to provide reliable and precise overcurrent protection for single-phase or specific split-phase AC lines. When a sustained overload or instantaneous short-circuit fault occurs in the circuit, it can quickly cut off the power supply, effectively protecting downstream wiring, sockets, and electrical equipment, preventing overheating, equipment damage, and fire risks caused by electrical faults. It is a fundamental and core component for ensuring electrical safety in residential, commercial, and light industrial applications.

Product Description

Frequently Asked Questions

What is the primary function of the OFGX 4P100A Residual Current Circuit Breaker?

The OFGX 4P100A provides robust protection against electrical shocks, insulation faults, overloads, and short circuits in three-phase electrical supply systems by quickly disconnecting the power when an earth leakage current is detected.

What does the "4P100A" specification stand for?

"4P" indicates a Four-Pole design, meaning it switches and protects all three phase lines plus the neutral line simultaneously. "100A" signifies a maximum continuous rated load current capacity of 100 Amperes.

Where is this high-performance circuit breaker typically installed?

It is ideal for commercial buildings, industrial facilities, and large residential main distribution boards requiring high capacity, reliable three-phase current protection.

How does residual current operation enhance electrical safety?

It continuously monitors the balance of incoming and outgoing electrical current. If an imbalance (leakage) occurs due to fault or human contact, the device trips in milliseconds, significantly reducing the risk of fatal injuries or electrical fires.

How frequently should the circuit breaker be tested?

It is recommended to test the unit monthly using the integrated test button to verify that the internal tripping mechanism operates smoothly and effectively.
