GE CR306D002 Nonreversing Magnetic Motor Starter

SKU CH-KN2B-8EFND

Three-pole non-reversing magnetic motor starter with thermal overload protection, DIN-rail mountable for 120V AC coil operation

  • TypePanelboard Mount
  • ColorTransparent
  • Thermal overload protection safeguards motors against overheating
  • Three-phase operation supports industrial power systems up to 600V AC
  • DIN rail mounting enables quick panelboard installation
  • Non-reversing design suits single-direction motor applications
  • 120V AC coil voltage matches standard control circuits

Industrial Motor Control Starter

The GE CR306D002 is a non-reversing magnetic motor starter designed for panelboard mounting on DIN rail. It provides three-pole overload protection for three-phase and single-phase motors in industrial control panels. The thermal overload design helps protect connected equipment from excessive current draw.

Open Enclosure Mounting Style

The unit carries no enclosure NEMA rating and features a transparent housing for visual inspection of contacts. Its panelboard-mount format allows direct installation onto standard DIN rails inside existing cabinets. This open construction suits builders who already provide their own rated enclosure and do not need a sealed starter housing.

120V AC Coil Voltage Requirement

The starter operates on a 120V AC coil and supports maximum motor voltages up to 600V AC. Three-phase horsepower ratings reach 25 hp at 480V and 600V, 15 hp at 240V and 10 hp at 208V. Single-phase ratings are 7 1/2 hp at 240V and 3 hp at 120V. Buyers whose control circuit runs on a different coil voltage cannot use this starter.

Questions about this item

How often will the thermal overload relay on the CR306D002 need inspection or replacement?

The thermal overload relay is a serviceable component; under normal duty it typically lasts many years, but heavy cycling or frequent trips will shorten its life and call for earlier replacement.

What is the first limit reached when the CR306D002 runs continuously at its 25 hp, 480 V AC three-phase rating?

The coil and contacts are rated for 120 V AC control and 600 V AC maximum; sustained operation at full 25 hp load will hit the thermal overload trip point before any voltage or coil limit is reached.

How much heat does the CR306D002 generate when mounted on a DIN rail inside a closed panelboard all day?

With a 120 V AC coil and 600 V AC rated contacts, the starter dissipates modest coil heat; the thermal overload element adds more heat under high current, so allow ventilation space around the DIN-rail mounting.
