What Are The Different Types Of Circuit Breakers Used For And How To Choose?
select:
1. Determine the Circuit Breaker category according to the rated current
⒉. Choose the circuit breaker series according to the protection function, namely: choose high-end products or low-end products
3. According to the selection of conventional circuit breakers, select specific models (current, voltage, breaking capacity, accessories, special functions, etc.)
Circuit breakers have different sequences and models to meet the needs of different physical environments (such as voltage, current, temperature, humidity, etc.). For the selected question, please use the answers to other questions
1. First select according to the rated voltage, and the rated voltage must be consistent. ⒉The rated current of the circuit breaker must be greater than or equal to the rated current of the circuit used. 3. The rated breaking current of the circuit breaker should be greater than or equal to the short-circuit current of the circuit used.
4. Choose according to environmental conditions (such as altitude, temperature, humidity), and then select a circuit breaker that meets the requirements. 5. According to the brand, select high-quality and cost-effective circuit breakers.
6. Check whether the circuit breaker has special opening conditions
