IDMT RELAY is a relay which is inverse time C/S at lower value of current & definite time C/S at higher value of current. In IDMT relay, when the value of current increases, the value of deflecting torque also increases and due to this operating time of relay decreases. That is why this relay is known as Inverse Definite Minimum Time(IDMT) relay. The Relay works in AC only.
