150HP 220A 480V NEMA 1 w/250A Breaker

Price: Call for price
Manufacturer: Motortronics
Model: BXLD-220-480-N

Choose this option for 150 Horsepower applications.

The FXLD-39-208-N Digital Soft Starter comes with a 1600A Breaker, Frame Size 1600

BXLD-220-480-N Digital Soft Starter is the ideal solution to electrical and mechanical problems that can occur when starting AC motors across the line. The BXLD 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 BXLD Series.

These starters are available in NEMA 1 and NEMA 12 enclosures. Call us for custom NEMA 4/4X enclosures.

Start It Soft - Work It Hard™

The BXLD 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.
