Overcurrent relay having a bimetal a resetting member and an accelerating mechanism

摘要

An accelerating mechanism in an overcurrent relay for accelerating the speed of moving operation of a resetting bar or the speed of motion in a normally closed contact caused by the resetting bar. In the application of the relay to any resetting mechanism, which effects resetting with a movement of the resetting bar, the relay can eliminate a very hazardous abnormal operation that a resetting operation is stored in a toggle mechanism, thus improving the safety of the resetting mechanism.
