CR306B004 - GE Magnetic Starter

CR306B004 - GE Magnetic Starter

The CR306B004 magnetic motor starter is built for straightforward, reliable motor control in 480V industrial systems where consistency matters more than complexity. Part of the well-known CR306 series, this unit is a NEMA Size 0, 3-pole starter designed for 480 VAC applications, supplied in an open configuration for installation inside a properly rated enclosure or control panel.

In everyday use, this is the type of motor starter you’ll typically find running HVAC equipment, pumps, compressors, conveyors, and general industrial machinery. It’s designed for full-voltage (across-the-line) starting, meaning the motor receives full power immediately when the coil is energized. That simple operation is still one of the most widely used methods in motor control because it’s predictable and easy to maintain.

Because it’s part of the CR306 family, the layout is familiar to most electricians and maintenance technicians. That matters when you’re replacing components or troubleshooting under pressure—you’re working with a design that’s already well understood in the field. The Size 0 frame keeps it compact enough for tighter control panels while still handling everyday light industrial motor loads without issue.

This unit is typically mounted inside a suitable enclosure, where it becomes part of a complete motor control system. Once installed and wired correctly, it’s the kind of component that just runs quietly in the background doing its job day after day.
