' Product Overview '
Made in the USA The Larson Electronics EXP-MTSTR-SF-3P-480V-5HP-7.5A-DCM-4X0.75S Explosion Proof Soft Starter provides reduced voltage starting solutions for industrial equipment in Class I, III and III rated environments. This 5 HP unit offers compatibility with 480V three-phase delta, 50/60 Hz. Multiple start, stop and control modes are available during use. Operators can mount the unit on surfaces, via four mounting legs at the back of the enclosure. The EXP-MTSTR-SF-3P-480V-5HP-7.5A-DCM-4X0.75S is an explosion proof reduced voltage starter, which can be used to soft start and preserve industrial motors inside combustible sites. This 5 HP unit is compatible with 480V three-phase delta, 50/60 Hz. The 7.5-amp soft starter is equipped with a squirrel-cage three-phase asynchronous motor. Starting times should not exceed 20 attempts per hour. This reduced voltage starter is protected by a copper-free aluminum enclosure with an aluminum lacquer paint finish. A weatherproof gasket enable the NEMA 3R/4 rated device to be used in both indoor and outdoor hazardous locations. The presence of corrosive gas or conductive heat may hinder the performance of the soft starter. The EXP-MTSTR-SF-3P-480V-5HP-7.5A-DCM-4X0.75S 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 explosion proof soft starter features the following operating modes and protective functionalities:
  • 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
  • Stop Modes: Soft Stop, Free Stop
  • 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
  • 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, Over Voltage 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
Hubs: This explosion proof unit comes with four 3/4" NPT hubs. Mount: The EXP-MTSTR-SF-3P-480V-5HP-7.5A-DCM-4X0.75S can be securely mounted on surfaces using four mounting legs located at the back of the enclosure. Applications: Hazardous locations, flammable environments, combustible systems, industrial motors, overload protection, reduced voltage starter, equipment preservation, pumps, manufacturing belts, inrush control, power monitoring and more.
