How does a Magnetic Overload Relay work?
Issue:
Understanding the theory of how a Magnetic Overload Relayworks
Product Line:
IEC Contactors and Starters
Environment:
Thermal Overload Relays
Resolution:
The Magnetic Overload relay has a movable magnetic core inside a coil which carries the motor current. The flux set up inside the coil pulls the core upwards. When the core rises far enough (determined by the current and the position of the core), it trips a set of contacts on the top of the relay.
