|Made in the USA The Larson Electronics MTSTR-3P-480-25HP-37A-120V.CTR-DCM Soft Starter provides reduced voltage starting solutions for industrial equipment. Equipped with a 120V contactor, this 25 HP unit offers compatibility with 480V (nominal, range of 430V-525V) three-phase delta, 50/60 Hz. Multiple start, stop and control modes are available during use, via a digital panel. Operators can mount the unit on walls or surfaces, via four screw holes at every corner of the soft starter. The MTSTR-3P-480-25HP-37A-120V.CTR-DCM is a reduced voltage starter, which can be used to soft start and preserve industrial motors. This 25 HP unit is compatible with 480V (nominal, range of 430V-525V) three-phase delta, 50/60 Hz. The 37-amp soft starter is equipped with a squirrel-cage three-phase asynchronous motor. Starting times should not exceed 20 attempts per hour. This unit comes with a 120V contactor, which is designed to facilitate the removal of AC line voltage from the unit. For electrical safety, the contactor can be set to open in the event of faults, resulting an interrupted power circuit and providing protection from full voltage power. The reduced voltage starter is protected by an IP20-rated enclosure. Cooling is provided by natural wind, making the unit suitable for indoor locations with adequate ventilation. The presence of corrosive gas or conductive heat may hinder the performance of the soft starter. The MTSTR-3P-480-25HP-37A-120V.CTR-DCM is designed for use at altitudes below 3,280.84 feet (1,000 meters). Above this range, the rate of power must be increased during operation. The industrial soft starter features the following operating modes and protective functionalities: â€¢ Start Modes: Current-limiting to Start, Voltage Ramp to Start, Torque Control + Current-limiting to Start, Torque Control + Voltage Ramp to Start, Current Ramp to Start, Voltage Current-limiting Double Closed-loop Start â€¢ Stop Modes: Soft Stop, Free Stop â€¢ Control Modes: Operation Panel Control, Operation Panel + External Control, External Control, External Control + COM Control, Operation Panel + External + COM Control, Operation Panel + COM Control, COM Control, No Start or Stop Operation â€¢ Protective Functions: Open Loop Protection for External Instantaneous Stop Terminals, Over-heat Protection for Soft Starter, Protection for Long Starting Time, Input Open Phase Protection, Output Open Phase Protection, Unbalanced Three-phase Protection, Starting Over Current protection, Running Overload Protection, Under Voltage Protection for Power Voltage, Overvoltage Protection for Power Voltage, Protection for Fault Parameter Setting, Load Short Circuit Protection, Auto Restart or Incorrect Wiring Protection, Incorrect Wiring Protection of External Control Stop Terminals Mount: The MTSTR-3P-480-25HP-37A-120V.CTR-DCM can be securely mounted on walls or surfaces. Four screw holes at every corner of the unit available for seamless mounting. Applications: Industrial motors, overload protection, reduced voltage starter, equipment preservation, pumps, manufacturing belts, inrush control, power monitoring and more.|
