Product Description

The GE Magnetic Motor Starter: Reversing (SKU 6VDN3, MPN CR309B104) is an enclosed reversing starter with thermal overloads, designed for three-phase applications. It features a 480V AC coil, NEMA Size 0 rating, 18 A capacity, and includes a pilot light for signaling. The starter requires 6 melting alloy thermal units (not included) for overload protection.

Frequently Asked Questions

What is the GE CR309B104 magnetic motor starter used for?

The GE CR309B104 reversing magnetic motor starter is used to control the forward and reverse rotation of three-phase industrial motors. It is commonly applied in conveyors, hoists, and machinery requiring directional changes. The enclosed design with thermal overloads protects motors from damage due to overcurrent conditions.

What are the specifications of the GE CR309B104 magnetic motor starter?

The GE CR309B104 is a NEMA Size 0 reversing starter with 3 poles, rated for 18 A at 480V AC coil voltage. It is a three-phase unit with a built-in pilot light for signaling. It requires 6 melting alloy thermal units (not included) for overload protection. The MPN is CR309B104.

Where to buy the GE CR309B104 magnetic motor starter worldwide?

You can source the GE CR309B104 reversing magnetic motor starter through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we provide reliable sourcing for this GE component.

How to select thermal units for the GE CR309B104 magnetic motor starter?

To select thermal units for the GE CR309B104, you must choose melting alloy units that match the motor's full-load current rating. The starter requires 6 units (not included). Refer to the motor nameplate and GE's thermal unit selection chart to ensure proper overload protection. Consult a qualified electrician for correct sizing.
