GE CR306A102 Magnetic Motor Starter

The GE CR306A102 is a non-reversing magnetic motor starter designed for three-phase industrial motor control. It operates with a 120V AC coil voltage and features three poles for switching three-phase loads. This starter suits panel builders and maintenance technicians needing reliable motor protection in automation systems.

Practical Voltage and Horsepower Limits

The starter handles maximum voltage ratings of 120V AC coil and up to 600V AC for motor circuits. Three-phase horsepower ratings are 2 hp at 600V AC, 2 hp at 480V AC, and 1 1/2 hp at both 240V AC and 208V AC. Single-phase ratings reach 1 hp at 240V AC and 1/3 hp at 120V AC. Exceeding these limits risks overload trips or contact welding.

DIN Rail Mounting and Wiring Considerations

The unit mounts on standard DIN rail for quick panel installation. Thermal overload protection requires correct heater element selection matching the motor full-load current. Common issues include undersized wiring for the 120V AC coil circuit and incorrect phase connections on the three-pole power terminals. Verify coil voltage matches control supply before energising.

Questions about this item

Should I pick the CR306A102 starter for a 208 V three-phase motor or a 240 V single-phase motor?

The CR306A102 handles 1½ hp at 208 V three-phase and 1 hp at 240 V single-phase, so match the starter to whichever motor voltage and phase you are wiring.

What does the 120 V AC coil rating mean when the starter is installed in a control panel?

The 120 V AC coil will pull in and hold the contactor when fed from a standard 120 V control circuit, letting the starter switch the motor load.

How does the NEMA starter style and DIN-rail mounting affect what enclosures I can use?

The NEMA-rated CR306A102 snaps onto standard DIN rail, so it fits directly into NEMA-type enclosures designed for rail-mounted motor starters.
