Abstract
In an overload relay, a tripping actuatorhas a first magnetand a moveable contact carrierhas a second magnetmounted opposed to the first magnet. A moveable contacton the moveable contact carrier is urged by repulsion between the magnets, to make a normally closed connection with a stationary contact, when the tripping actuator is in an ON positionand the contact carrier in a first stable position'. The magnets pass through an over-center tripping position (T) when the tripping actuator is moved to an OFF positionin response to an overcurrent condition sensed by a bimetallic thermal overload sensor. The magnets repel each other after passing through the over-center tripping position, to thereby urge the moveable contact into a second stable position, away from the stationary contact, to break the normally closed connection with the stationary contact.
