熱動形過負荷継電器
Document Type and Number:
Japanese Patent JP4706772
Kind Code:
B2
Abstract:
A thermal overload relay includes a main bimetal for detection of an overload current, a shifter associated with the main bimetal, a release lever working according to a displacement of the shifter, a contact reversing mechanism for changing-over contacts by reversing action caused by rotation of the release lever, and a manipulation structure for manipulating the release lever and the contact reversing mechanism. The manipulation structure includes a reset bar for returning the contact reversing mechanism to an initial state. The reset bar is arranged to change-over between a manual reset state in which the reset bar can be pushed-in and an automatic reset state in which the reset bar is pushed-in and turned from the manual reset state and held in that state.
