Thermal type overload relay |
摘要 |
A thermal-type overload relay which uses a bimetallic element for sensing overload currents includes a shifter controlled by the bimetallic element to shift a release lever to which is attached a spring. The spring controls a movable board which has two reversible stable positions corresponding respectively to turn off or on a pair of normally open contacts and a pair of normally closed contacts.The movable board is a molding of insulated material carrying a pair of spaced insulated contacts and also includes a segment which is externally visible to display an indication of which pair of contacts is open and which is closed.
