Decoding the DZ47 Breaker: A Comprehensive Guide for the Chinese Market

The DZ47 breaker is a common miniature circuit breaker (MCB) found extensively in the Chinese electrical market. Understanding its variations and specifications is crucial for choosing the right breaker for specific applications. This guide delves into the technical details, types, and applications of DZ47 breakers from various manufacturers like Andeli Group (www.andeligroup.com), Delixi (www.cn-delixi.com), Singi Electric (www.singielectric.com), NBSe Electric (www.nbse-electric.com), and Changan Electric (www.changanelectric.com).

Understanding the DZ47 Breaker

DZ47 breakers are miniature circuit breakers designed to protect electrical circuits from overloads and short circuits. They are commonly used in residential, commercial, and industrial settings. The “DZ47” designation indicates a specific design standard followed by manufacturers across China. These breakers are known for their compact size, ease of installation, and relatively low cost. They typically offer thermal-magnetic tripping mechanisms, providing protection against both gradual overloads and sudden short circuits.

FAQs

1. What is the difference between thermal and magnetic tripping?

Thermal tripping protects against overload currents, which gradually increase over time. Magnetic tripping protects against short circuits, which are sudden, high current surges.

2. How do I choose the correct rated current for my DZ47 breaker?

The rated current should be slightly higher than the maximum expected current draw of the circuit it protects. Refer to the load’s specifications.

3. What does the “P” in 1P, 2P, 3P, and 4P signify in DZ47 breakers?

It indicates the number of poles: 1P (single-pole), 2P (double-pole), 3P (three-pole), and 4P (four-pole).

4. What are the common tripping characteristics (B, C, D) for DZ47 breakers?

These letters indicate the breaker’s sensitivity to overcurrent. ‘B’ is for low currents, ‘C’ is for medium currents, and ‘D’ is for high currents.

5. Where can I find more detailed information on specific DZ47 breaker models?

Detailed specifications and datasheets are available on the manufacturers’ websites, such as www.cn-delixi.com, www.singielectric.com, and www.nbse-electric.com. Always refer to the manufacturer’s documentation.
