Thermal overload relays are protection devices required in various motor starter combinations. L&T Electrical & Automation’s range of contactors complements the range of thermal overload relays. These are available for various DOL/ Star delta combinations. The overload relays have a built-in sensitive mechanism that protects the motor from overload and single phasing.
