ABB CR305C002 – Frequently Asked Questions
1) I need a contactor to switch lighting circuits, not a motor. Is the ABB CR305C002 the right choice?
The ABB CR305C002 is described for switching and control of electrical loads in control panels, motor circuits, and switching assemblies. For a dedicated lighting panel, a purpose-built lighting contactor is the more direct fit: the Square D 8903L Series Type L is a multipole lighting contactor, electrically held, 8-pole, 30A, 600V, and the Square D 8903S Type S is an electrically held lighting contactor in a 3-pole configuration. Pick the 8903L when you are switching a large bank of lighting branch circuits and the 8903S when the job is a smaller three-pole lighting load.
2) What is the exact ABB part number for this contactor, and how many come in a pack?
The manufacturer part number is CR305C002, an ABB contactor, and it is supplied as a single unit, 1 EA. That matters for panel builders and MRO stockrooms ordering one-for-one replacements rather than a multi-pack.
3) What is the difference between the ABB CR305C002 contactor and a Square D 8910 definite purpose contactor?
The ABB CR305C002 is a contactor for switching and control of electrical loads in commercial and industrial control panels, motor circuits, and switching assemblies, supplied 1 EA. The Square D Class 8910 is a definite purpose contactor, a family built around specific duty applications such as HVAC and refrigeration equipment rather than general panel switching. If you are replacing a contactor inside a packaged unit that originally carried a definite purpose part, the 8910 family is the closer match; for general motor control and switching work in a panel, the CR305C002 is the type to look at.
4) What is the difference between the Square D 8903L and 8903S lighting contactors if I am cross-shopping against the ABB CR305C002?
Both Square D units are electrically held lighting contactors, but they cover different pole counts. The 8903L Series Type L is a multipole unit rated 8-pole, 30A, 600V, while the 8903S Type S is a 3-pole contactor. The ABB CR305C002 sits in a different lane from either, being a contactor for motor control and general switching in commercial and industrial panels rather than a lighting-specific device. Match on the number of circuits you are switching first, then on the load type.
5) Is there an open-style contactor alternative to the ABB CR305C002 for mounting inside an existing enclosure?
The Square D 8910DP definite purpose contactor is offered in an open construction, which is the version panel builders use when the contactor is going inside an enclosure that already provides the protection. The ABB CR305C002 is a contactor intended to fit into standard electrical panels and control assemblies as part of a broader switching or motor control setup. Confirm the coil voltage and current rating you need before swapping between the two families, since they are different product lines.
6) A lighting contactor looks like the same part as the ABB CR305C002. Can I use one in place of the other?
They look similar on a DIN rail but they are not interchangeable by default. The Square D 8903L and 8903S are electrically held lighting contactors, built for the inrush and duty cycle of lighting branch circuits, with the 8903L at 8-pole, 30A, 600V. The ABB CR305C002 is a contactor for motor control and switching duty in commercial and industrial panels. Substituting across those categories changes the pole arrangement and the intended load, so match the replacement to what the panel schedule actually calls for rather than to the physical look of the old part.
7) Can I standardize my facility's control panels on ABB contactors like the CR305C002?
That is a common approach for facility and MRO teams. Ordering by ABB part number CR305C002 in single units lets you keep one line item on the shelf per panel position instead of mixing brands, which simplifies spares and troubleshooting across control and switching infrastructure. Just confirm the coil voltage and contact rating on the unit you are replacing matches before you swap, since those are stamped on the device in the panel.
