Electrical overload circuit breaker switch has movable contact operated linearly by actuator

摘要

The electrical overload switch has a pair of fixed contact shoes (2,3)and between them is a movable contact (4). The contact is moved by a mechanism (8) that is released when the current exceeds a set level to open the contacts. The actuator has a rod (27) that moves linearly, operating through a contact shoe (6) to connect with the movable contact.
