Product Overview

The TA25DU1.0 is a 3-pole 630mA Thermal Overload Relay for use with the starter construction. It is designed for close couple mounting and reset can also be adjusted to function as a stop button. The motor current flows through its bimetals (1 per phase) which is indirectly heated. Under the effect of the heating, the bimetals bend cause the relay to trip and the position of the auxiliary contacts to change. The relay is built to be self protecting in the event of an overload until the short circuit protection device is activated.
