Frequently Asked Questions (FAQs)

Frequently Asked Questions About Circuit Breaker Factories in China?

1. What are the key differences between standard and economical grade circuit breakers?

You might be wondering about the differences between standard and economical grade circuit breakers. The main difference lies in their certifications and features. Standard circuit breakers, like those from Auber Instruments, are UL1077 listed, meaning they meet the Underwriter Laboratories standard. Economical grade breakers, on the other hand, have CE approval and meet the IEC/EN 60898-1 Standard. Economical breakers lack a color indicator and have a lower short-circuit breaking capacity, but they are sufficient for small household applications.

2. How do I choose the right type of circuit breaker for my needs?

Choosing the right type of circuit breaker can be daunting, but it’s crucial for safety. First, consider the branch current and total current of your electrical setup. You’ll need to choose a breaker that matches these specifications. Additionally, think about the type of load you’re protecting—e.g., lighting, appliances, or motors. Curve types like B, C, and D designate the instantaneous trip current range, so select one that fits your application.

3. What are the common specifications for circuit breakers in China?

In China, circuit breakers come in various specifications, especially in the DZ series. Common models include C16, C25, C32, C40, C60, C80, C100, and C120. For industrial use, you’ll find DW and DZ models with ratings up to 1000A or more. These specifications help ensure the breaker can handle the required electrical load safely.

4. Which Chinese companies are known for producing high-quality circuit breakers?

China is home to several reputable circuit breaker manufacturers. Companies like Wenzhou Korlen Electric Appliances Co., Ltd., TAIXI Electric Co., LTD, and Shanghai Dada Electric Co., Ltd. are well-known for producing high-quality circuit breakers. These companies offer a range of products, including miniature circuit breakers, residual current circuit breakers, and molded case circuit breakers.

5. What is the new GB/T 17701-2023 standard for circuit breakers in China, and why is it important?

The GB/T 17701-2023 standard is a new regulation for circuit breakers in China, effective from April 1, 2024. This standard applies to mechanical switchgear designed for household and similar applications, ensuring the protection of internal wiring and components. It includes revised inspection items, new requirements for marking and mechanical design, and additional test procedures. Compliance with this standard is crucial for ensuring the safety and reliability of electrical equipment.
