The wiring terminals on the SPDT models are color coded:

  • Red is common.
  • The red to yellow circuit closes on temperature increase.
  • The red to blue circuit opens on temperature increase.

Refer to Figure 1 and Figure 2 for terminal identification and typical wiring connections.

When the reset lever is pressed during normal operation, the trip free contacts are activated, the red to blue contact opens and the auxiliary red to yellow contact closes. At this point, the auxiliary system will activate.
