XLD-1250-208-N Digital Soft Starter is the ideal solution to electrical and mechanical problems that can occur when starting AC motors across the line. The XLD series utilizes stepless motor acceleration and full control over inrush current and starting torque.

High starting currents, slipping belts, gear box damage, pressure waves in pipes, sudden conveyor jolts, and premature motor failures will be a thing of the past with the Motortronics XLD Series.

These starters are available in Panel mount, NEMA 1, NEMA 12, and NEMA 4/4X.

Start It Soft - Work It Hard™

The XLD soft starters are suited for new installations and replacement of existing starters.

Both models provide motor overload protection and can be supplied as a combination starter with a shunt trip circuit breaker or disconnect option. (Make sure you call us for these customizations)

Also, make sure you choose the XLD-KPN1 or XLD-KP12 external keypads as an add on to meet your needs.

Cooling Convection up to 180A, fan assisted 62 - 120A, Fan ventilated 220 - 1250A Bypass Contactor Shunt rated contactor included as standard in all NEMA 12 enclosed units 92A and above. Also standard with all NEMA 12 combination starters. Line start rated contactor available as an option. Ambient Condition Design Chassis units: 0° to 50 °C (32° to 122°F) Enclosed units: 0° to 40°C (32° to 104°F) 5 - 95% relative humidity 0 - 3300 ft. (1000m) above sea level without derating Control 2 or 3 wire 120VAC (customer supplied) Optional 240VAC control voltage and CPTs are available. Auxiliary Contacts Type / Rating: Form C (SPDT), rated 5 Amps, 240VAC max. (1200VA) 3 Programmable Relays Fault Indicator: AC triac solid state switch 240VAC, 50mA max. Approvals UL Listed, Canadian UL (cUL) Listed Advanced Motor Protection Two Stage Electronic Overload Curves Starting: Programmable for Class 5 through 30 Run: Programmable for Class 5 through 30 when "At-Speed" is detected. Overload Reset (Note 1) Manual (default) or automatic Retentive Thermal Memory Overload circuit retains thermal condition of the motor regardless of control power status. Unit uses real time clock to adjust for off time. Dynamic Reset Capacity Overload will not reset until thermal capacity available in the motor is enough for a successful restart. Starter learns and retains this information by monitoring previous successful starts.
