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