OEM OFDZ47 Series 4P Miniature Circuit Breaker Factories, Supplier

The OFDZ47 Series 4P (Four-Pole) miniature circuit breaker is a full-pole protection device specifically designed for three-phase, four-wire (3P+N) low-voltage distribution systems. Its core design adheres to international electrotechnical standards, such as IEC 60898, and aims to provide synchronized overload and short-circuit protection for all three phase conductors (L1, L2, L3) and the neutral conductor (N) through an integrated mechanical linkage mechanism. It achieves complete electrical isolation of the circuit. This product is a key component for preventing system risks caused by neutral conductor faults or abnormal potential, ensuring power supply safety for sensitive loads, and meeting the highest-grade safety isolation standards. It is particularly suitable for distribution scenarios in industrial, commercial, and data center applications that have stringent requirements for power supply continuity, safety, and isolation integrity.

Product Description

Frequently Asked Questions

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

The OFDZ47 series miniature circuit breaker is engineered for overload and short-circuit protection in low-voltage electrical distribution networks, providing high reliability for lighting and power circuits in commercial and residential settings.

What is the functional difference between 1P and 2P models?

A 1P (Single Pole) circuit breaker disconnects only the live wire during a fault, suitable for single-phase 230V circuits. A 2P (Double Pole) breaker switches both live and neutral lines simultaneously, offering enhanced isolation and complete circuit disconnection.

How does the OFDZ47 MCB protect against electrical overload?

It features a thermal-magnetic tripping mechanism. The thermal element trips the breaker when continuous over-current causes temperature buildup, while the magnetic element instantly interrupts severe short-circuit currents.

Is the OFDZ47 series compatible with standard electrical enclosure DIN rails?

Yes, all OFDZ47 models feature a modular design compatible with standard 35mm DIN rail mounting, enabling effortless installation into distribution boards and consumer units.

How do I select the right current rating for my application?

The rated current should be selected based on the total continuous load current of the downstream equipment while staying within the maximum current carrying capacity of the circuit wiring.
