China OFDZ47 Series 2P Miniature Circuit Breaker Factory, Supplier

The OFDZ47 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 an internal, mechanically linked mechanism that ensures 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 fundamentally eliminates the safety hazards associated with a potentially live neutral conductor that can occur when only the line conductor is interrupted. It is particularly suitable for power distribution applications with explicit requirements or code-mandated regulations regarding operational safety, fault isolation integrity, and power supply continuity. It is a key component for elevating the protection level of single-phase circuits.

Product Description

Frequently Asked Questions

What is the primary function of the OFDZ47 Miniature Circuit Breaker?

The OFDZ47 Miniature Circuit Breaker (MCB) provides advanced protection against electrical overloads and short circuits, protecting devices and wiring systems from thermal and electrical damage.

What is the difference between 1P and 4P OFDZ47 Miniature Circuit Breakers?

A 1P (Single Pole) breaker is designed for single-phase electrical lines suitable for basic residential loads. A 4P (Four Pole) breaker controls three phase lines along with the neutral wire, ideal for commercial or industrial applications.

Why choose an MCB over a traditional fuse?

Unlike standard fuses which melt and must be replaced after tripping, an MCB can easily be reset manually after resolving the fault, reducing system downtime and operational costs.

Where are OFDZ47 series circuit breakers commonly applied?

OFDZ47 series breakers are widely utilized in residential distribution boxes, commercial property power control units, and industrial automation equipment demanding precise circuit breaking capability.

How do I select the right OFDZ47 specification for my installation?

Select the appropriate model based on total operating current, working voltage, expected fault conditions, and whether your distribution system requires single-phase or multi-phase protection.
