Protect your industrial equipment against sudden power surges with this soft start torque controller from Rockwell Automation. It intercepts high-voltage inputs and gradually feeds them through to ensure that your device switches on every time. The three-phase controllers have a unique-sequence-detection protective feature that turns the output off in the event of an incorrect motor phase. Thanks to an abrasion-resistant semi-crystalline plastic housing, so you can be sure of a long service life. This unit is suitable for demanding processes that need a smooth start, from compressors, elevators and grinders to paint shakers and car washes.
