The Klockner Moeller EMT6 (230V) Thermistor Overload Relay is a compact, high-reliability protection unit designed to protect electric motors against thermal overloads. Capable of operating on AC 230V 50/60Hz, the EMT6 finds extensive application in motor protection circuits, avoiding overheating damage by monitoring PTC thermistors built into motor windings. With a high tightening torque of 1.2 Nm, support for AWG 20–14 conductors, and conformity to IEC 947 / IEC 34-11-2 Type A, it provides reliable performance in industrial usage. With a thermal current (Ith) rating of 6A and a Uimp rating of 6000V, it provides robust electrical endurance in rigorous usage conditions. Its weight of only 250 grams makes it perfect for incorporation in space-constricted control panels.
