Abstract: The short-circuit test of miniature circuit breakers, as an indispensable test item for product certification, is of great importance to manufacturers and customers. Combining the actual testing experience, the author analyzes and gives examples of the influencing factors of the short circuit test of the circuit breaker (small circuit breaker) specified in GB/T 10963.1. Also, the author pointed out that manufacturers should comprehensively consider customer requirements, production costs, standard regulations, etc., to determine the rated current, rated short-circuit current, contact material and size of their products, and try to optimize the product.
Key words: circuit breaker; short-circuit test; influencing factor
