What is the recommended contact distance for circuit breaker contacts according to industry standards?
5 answers
Industry standards recommend specific contact distances for circuit breaker contacts to enhance performance and longevity. According to the research data, the optimal contact distance ranges vary based on different aspects. The first contact part of the movable contact should be in contact with the first contact part of the fixed contact, while the distance between the second contact parts should be greater than 2 mm. Additionally, the distance from the lock catch point to the spring locating point of the moving contact should not exceed 9mm, and the distance to the contact surface in contact with the fixed contact should be less than 2.5mm. Moreover, a parallel opposite distance (L) between moving and static contacts ranging from 13.6 to 50mm is recommended for effective breaking capacity and improved product performance. These specifications aim to reduce electric burning loss, prolong the breaker's life, and enhance its breaking capacity.
