TA DU Thermal Overload Relays

TA25DU…TA200DU series thermal overload relays are economic electro mechanical protection devices for the main circuits, they offer reliable protection for motors in the event of overload or phase failure, the devices have trip class 10A.
■ Manual or automatic reset selected;
■ Phase loss sensitivity according to IEC 60947-1;
■ Two electrically isolated auxiliary contacts, 1NO+1NC;
■ Test and stop function, trip indication on the front;
■ Temperature compensation;
■ Suitable for three and single-phase applications;
The thermal overload relays are three-pole relays with bi-metal tripping elements, the motor current flows through the bi-metal tripping elements and heats them directly and indirectly, in case of an overload, over current, the bi-metal elements bent as a result of the heating, this leads to a release of the relay and a change of the contacts switching position.
