Square d circuit control thermal overload relay a 1.39
Here is a overload thermal relay unit made by Square D.
This is a A 1.39 Thermal OVERLOAD RELAY.
This is a melting Alloy Thermal Unit (heater)
This unit is used as a one piece nontamperable unit for Electric motor protection in the starter control circuit.
Once tripped, the thermal overload relay will not reset until it has cooled, automatically allowing the motor to cool before it can be re-started.
I offer a money back 7 day refund as long as the coin is returned in the original untouched holder.
