WebA thermal overload relay is a safety device used in manual control circuits. The thermal overload uses an electric motor to control its overheated short circuit by switching off the heating circuit when the temperature increases above the set value. This type of thermal overload relay will be used if there is the possibility of a short circuit ... WebOnce tripped, the thermal overload relay will not reset until it has cooled, automatically allowing the motor to cool before it can be re-started. NOTE: The overload relay must be used in conjunction with a contactor. The overload relay has no power contacts and cannot disconnect the motor by itself. saints wear for womenWebOverload Relay, Mini Thermal, K, 3.7 A, 5.5 A, TeSys. SCHNEIDER ELECTRIC.
