A wide range of bi metal thermal overload relays are offered for close protection of motors & other inductive loads against overload, single phasing & unbalanced system voltages.
Thermal Overload Relays are ambient temperature compensated and are independent of variation in ambient temperature. Protection against single phasing & unbalanced voltages has been provided by means of differential tripping mechanism which ensures positive protection of motors / loads. They are provided with 1NO + 1NC potentially free contacts which can be used for signaling. The relay can be used in either Auto or Manual reset mode.Protection against overload & single phasing
