CR306B003 - GE Magnetic Starter

CR306B003 - GE Magnetic Starter

The CR306B003 magnetic motor starter is a straightforward, commonly used unit for everyday motor control. It’s part of the CR306 series, built as a NEMA Size 0, 3-pole starter with a 240V AC coil, and it’s typically installed inside a panel or enclosure as part of a complete motor control setup.

In practice, this is the kind of starter you’ll find running HVAC systems, pumps, compressors, conveyors, and general industrial equipment. It’s designed for full-voltage starting, so when the coil is energized, the motor gets full power right away. When it drops out, the motor shuts down cleanly. Nothing complicated—just standard motor control that’s been used for years because it works.

Since this is an open-style unit, it gives installers flexibility to mount it inside existing control panels or enclosures. It’s also a familiar layout for anyone who works regularly with CR306 components, which helps a lot when you’re replacing parts or working under time pressure.

The Size 0 frame keeps it compact enough for tighter spaces, while still handling light industrial motor loads. The 240V coil is a common control voltage in commercial and industrial systems, so it tends to drop into existing setups without much adjustment.

At the end of the day, this is the type of motor starter most people don’t think about once it’s installed—it just does its job in the background.

Material Compliance and Certifications

The CR306B003 is built for industrial motor control use and meets standard compliance requirements for electrical equipment in commercial and industrial environments. It carries UL and cULus certification (E1811) and is intended for installation in properly rated systems following applicable electrical codes. It also aligns with common industry standards including REACH, TSCA, and WEEE (Business-to-Business classification).

Where It Works Best

• HVAC systems and air handling units
• Industrial pumps and water systems
• Compressors and refrigeration equipment
• Conveyor and light material handling systems
• OEM machinery and control panels
• Replacement of existing CR306 Size 0 starters
• General indoor motor control applications

The CR306B003 is one of those parts that gets installed and then mostly forgotten about—in a good way. It just runs the motor reliably in the background, which is exactly what it’s supposed to do.
