TL Torque Limiters regulate current on one of the three motor phases to control the torque being applied to the motor, allowing for smooth starting of a motor. Designed to be used with a Manual Motor Starter or a Full Voltage Starter, they provide necessary over-load protection and line isolation for the motor. These easy-to-install, compact devices are rated up to 25A, for controlled acceleration and deceleration of fractional to 15 hp/11 kW motors at 480/400 Vac.
