The Larson Electronics MTSTR-MV-3P-4160V-400A-V1 Medium Voltage Soft Starter provides reduced voltage starting solutions for industrial equipment. This unit offers compatibility with 4000/4160V three-phase 50/60 Hz. Overload, over current, phase imbalance, renentive thermal memory, load loss, coast-down lock out timer and starts-per-hour lock out timer protection are provided by the device. Equipped with a control voltage of 110-120V, the 50-2740 HP unit can be mounted on walls or surfaces.
The MTSTR-MV-3P-4160V-400A-V1 is a medium voltage reduced voltage starter, which can be used to soft start and preserve industrial motors that accepts medium voltages. This 3-wire, solid ground unit is compatible with 4000/4160V three-phase 50/60 Hz. The 50-2750 HP soft starter is equipped with a control voltage of 110-120V. This unit contains eight relays and four programmable auxiliary contacts. Operators may access an alphanumeric LCD display with eight function keys for controlling the settings of the device. A total of twelve LEDs serve as status indicators on the medium voltage soft starter for real-time monitoring. Operators may record up to 60 events for data logging and saving.
The MTSTR-MV-3P-4160V-400A-V1 supports numerous protective functions:
• Overload: Manual or Auto Reset
• Over Current: 100-300% of Motor FLA Trip Level w/ 1-20 sec Trip Delay
• Phase Current Imbalance: 5-30% Trip Level Between Phases w/ 1-20 sec Trip Delay
• Retentive Thermal Memory
• Load Loss: Under Current 10-90% of Motor FLA Trip Level w/ 1-60 sec Trip Delay
• Coast Down Lock Out Timer: 1-60 Mins
• Starts-per-Hour Lock Out Timer: 1-6 Successful Starts per Hour w/ 1-60 mins Between Start Attempts
The reduced voltage starter is protected by a heavy-duty enclosure. Cooling is provided by forced natural wind, making the unit suitable for locations with adequate ventilation. The presence of corrosive gas or conductive heat may hinder the performance of the soft starter. Recommended environments include: 5-95% non-condensing humidity, locations with vibrations less than 0.5G and elevations between 0-3,330 feet (w/o derating).
Mount: The MTSTR-MV-3P-4160V-400A-V1 can be securely mounted on walls or surfaces.
Applications: Industrial motors, overload protection, reduced voltage starter, equipment preservation, pumps, manufacturing belts, inrush control, power monitoring and more.
