Omron J7TKN-A-1E8 Thermal Overload Relay, Safety Relay, Acti

The Omron J7TKN-A-1E8 is a thermal overload relay classified under safety relays, designed to protect motors and circuits from sustained overcurrent conditions by mimicking the heating characteristic of the load. It sits in the Circuit Breakers, Fuses & Protection top category, meaning it's a protective device, not a switching relay — it trips an auxiliary contact when the thermal element reaches its threshold, typically wired in series with a contactor coil to drop the load.
