DZ47 3 Pole 32A AC Circuit Breaker

As a leading manufacturer and supplier of DZ47 3 Pole 32A AC Circuit Breaker in China, PUGAO (Plannter Electric) has been specialized in producing low-voltage electrics since its establishment in 2011, and its products are exported to more than 20 countries and regions, such as the Middle East, Central Asia, Africa and Southeast Asia. We have passed ISO9001 international quality management system certification, CE, CCC and many other authoritative certificates. Whether it is industrial motor control, commercial building power distribution, or new energy power station supporting, PUGAO can provide efficient solutions.

Product Advantages

Although the DZ47 is a general-purpose series, PUGAO has significantly elevated its performance—far surpassing that of ordinary products—through the use of premium materials and upgraded manufacturing processes.

1. Copper-Silver Composite Contacts

Unlike the silver-plated copper or pure copper contacts commonly found on the market, we utilize silver-nickel alloy contacts. These contacts feature low contact resistance and exceptional resistance to arc erosion, ensuring an operational lifespan of 10,000 cycles.

2. Highly Flame-Retardant Housing

The housing is constructed from nylon rather than inexpensive ABS plastic. This provides superior thermal stability, preventing the housing from melting under the extreme temperatures generated during a short circuit; it meets the UL94 V-0 flame retardancy standard.

3. True Three-Phase Linkage

The internal mechanism of the DZ47 3-Pole 32A AC Circuit Breaker employs a linkage system that ensures the simultaneous switching (on/off) of all three phases—L1, L2, and L3. This prevents accidents involving motor burnout caused by single-phase operation resulting from the premature disconnection of a single phase.

4. Modular Design

We have adopted a standard 35mm DIN rail mounting design. Despite its powerful functionality, the unit maintains a compact form factor, facilitating easy installation within confined distribution boxes.

Usage Precautions

1. Strictly Match Rated Current to Load

The DZ47 3-Pole 32A AC Circuit Breaker has a rated current of 32A. Ensure that the actual load remains within a reasonable range; prolonged operation under overload conditions is strictly prohibited. Failure to observe this may result in frequent tripping, accelerated aging of internal components, and, in severe cases, complete device failure.

2. Must Be Used in Three-Phase Electrical Systems

This 3-pole circuit breaker is designed for use in three-phase circuits (L1/L2/L3); it is not recommended for use as a substitute in single-phase circuits.

During operation, ensure that the distribution of the three-phase load is as balanced as possible to avoid unbalanced load operation.

3. Correct Wiring

All wiring terminals must be securely tightened to prevent loose connections. It is recommended to use conductors that meet the appropriate specifications (determined based on the actual load). Poor wiring connections can lead to overheating and may even result in the burnout of the circuit breaker.

4. Installation Environment Requirements

The device should be installed within a dry and well-ventilated distribution box. Avoid installation in environments characterized by high temperatures, excessive humidity or moisture, or the presence of corrosive gases; implement additional protective measures if necessary.

5. Regular Inspection and Maintenance

Periodically check the terminals to ensure they remain tight. Observe the device for any signs of scorching, discoloration, or unusual odors. Additionally, manually operate the circuit breaker at regular intervals to verify that its mechanical structure is functioning correctly.
