Soft Starters

Soft Starters are the future of motor control and protection

While motor protection, in the form of a standard contactor/overload, has been around for well over a hundred years, soft starters now offer enhanced motor protection for standard and high torque applications. With the options for multiple starting modes and off-site monitoring, soft starters offer the flexibility and reliability that is not available with a standard starter set. The low voltage soft starter series offers AMP ranges from 27 up to 838 AMPS and horsepower ranges from 20 to 700 H.P. at 460 volt.

Benshaw Soft Starters are the industry leader

With the introduction of the new MX2 and MX3 technology in late 2006, Benshaw soft starters took the lead in industry innovation and design. With CE, UL, CUL and NEMA compliance along with Built-In self testing, no other soft starter on the market today can match Benshaw's reliability, feature set and performance in their RB2, RB3, RX2E or RX3E lines of open chassis and enclosed starters. This combined with Benshaw's award winning technical support and 3-year warranty, no other option exists in the market today that would better suit your application for motor protection. Shop our low and medium voltage soft starters for sale below.
