UL508A Air Handling Motor Starters

c3controls’ Electrical Engineers have designed enclosed motor starters specifically for air handling applications, and each are Listed per UL508A, the Standard for Industrial Control Panels.

Our UL508A air handling motor starters come in two frame sizes:

For over 40 years, c3controls has been a leading manufacturer of quality motor controls for the industry. As a Certified UL508A Panel Builder, and because we strictly control the manufacturing of our products, we can provide you with a high quality motor starter that you can install and forget about for years to come.

Our UL508A Type E Combination Direct-On-Line (DOL) Starters provide motor disconnect, short-circuit and ground fault protection, motor control, and motor overload protection. Each assembly includes a polycarbonate enclosure, motor protection circuit breaker, contactor, miniature circuit breaker, and 22mm IEC pilot devices.
