China OFD4Z7 Series 2P Miniature Circuit Breaker Suppliers, Manufacturers

The OFD4Z7 Series 2P (Double-Pole) miniature circuit breaker is a full-pole protection device specifically designed for single-phase AC distribution systems. Its core design incorporates a mechanically linked mechanism, ensuring the synchronized interruption of both the line (L) and neutral (N) conductors. This product not only provides precise overload and short-circuit protection but also achieves complete electrical isolation of the circuit. It effectively eliminates potential safety risks associated with an unbroken neutral conductor, offering critical protection for application scenarios with high requirements for operational safety and isolation integrity.

Product Description

Frequently Asked Questions (FAQ)

What is the main function of the OFD4Z7 Series Miniature Circuit Breaker?

The OFD4Z7 series circuit breaker provides essential overcurrent and short-circuit protection for electrical equipment and circuits in industrial, commercial, and residential environments.

What is the difference between 1-Pole (1P) and 4-Pole (4P) circuit breakers?

A 1P circuit breaker protects a single live phase line in a standard circuit, while a 4P circuit breaker is designed for three-phase systems plus neutral, offering comprehensive isolation and fault protection across all four lines.

Are OFD4Z7 circuit breakers suitable for industrial-grade applications?

Yes, the OFD4Z7 series is engineered with robust thermal-magnetic protection mechanisms and high breaking capacity, making it suitable for demanding industrial-grade overcurrent protection requirements.

How do I choose the correct current rating for an MCB?

Select a rated current (In) that matches your load requirements without exceeding the current-carrying capacity of the circuit wiring. Consult electrical standards or a certified electrician for exact sizing.

What mounting standard does this product line support?

OFD4Z7 series miniature circuit breakers feature standard 35mm DIN rail mounting for convenient, snap-on installation inside standard distribution boxes and switchboards.
