ABB CR306D002 Industrial Relay Module

ABB CR306D002 is a 3-pole magnetic motor starter (NEMA size 2) with an integrated overload relay, intended for starting and protecting three-phase motors in industrial control panels. The coil is 120 VAC, while the unit supports line voltages up to 600 VAC and is rated to carry 45 A, making it suitable for medium-duty motors in compact control panels. This starter is listed in standard catalogs as an open, open-frame device, designed to be panel-mounted with the enclosure provided by the control cabinet. A closely related variant, CR306D002LTH, appears in ABB’s e-catalog, indicating a compatible form factor within the CR306 family. Some catalog entries describe the coil as encapsulated in certain configurations, paired with a three-leg overload relay that protects all phases. Typical applications include starting and protecting small to medium three-phase motors in conveyors, pumps, fans, and general machine control, where a compact, plug-in starter simplifies replacement and wiring in control panels.
