4 terminal device with Relay Trip (Current Circuit) type F

over load through pins 3 to 4 , causes contacts to open between 1 and 2 

Relay Trip

The Relay Trip configuration is a four-terminal device, where the contact and coil circuits are electrically isolated but mechanically linked. An overload in the coil circuit will cause the contact circuit to open. These circuits may be of opposite polarity, and are commonly used in "dump" circuit, "panic" circuit, and remote shutdown applications. (Note: World Approval Agencies may require a more electrically isolated voltage coil pole for this function, see "Series Trip with Remote Shutdown" circuit.)
