TA25-TA450 Class 10 Thermal Overload Relay

ABB

Thermal overload relays are used in connection with contactors A, AF, AE, TAE, BC and TBC to protect motors with a rated operating voltages up to 690 V a.c. and 800 V d.c. The thermal overload relays are three-pole relays. They have bimetallic releases (1 per phase) through which the motor current flows and are indirectly heated. The bimetallic releases bend subject to the influence of heating and this results in tripping of the relay.The auxiliary contacts change their switch position. The relays feature a setting scale in Amperes. In compliance with internationnal and national standards, the setting current is the rated motor current and not the tripping current (no tripping at 1.05 x I setting current, tripping at 1.2 x I setting current ).
