Eaton C320KGS5 – Frequently Asked Questions

1) What contact arrangements does the Eaton Freedom side-mount auxiliary contact come in?
Four orderable parts. C320KGS1 is a 1NO circuit, C320KGS3 is 1NO-1NC, and C320KGS5 and C320KGS22 are standard circuit blocks. Pick the NO/NC count your control scheme needs before ordering, since the block is not field-convertible between part numbers.
2) What are the alternatives if my contactor is not an Eaton Freedom?
The C320KGS block is built for the Eaton Freedom platform and will not mount on other makes. For ABB contactors and relays, the CR305X series auxiliary contact is the equivalent add-on block. For a Square D fusible switch needing an isolated alarm circuit, the Type S isolated alarm contact kit covers it, and Bussmann's BAC series auxiliary contact is the option on the fuse side.
3) Can an ABB CR305X auxiliary contact be used in place of an Eaton C320KGS on a Freedom starter?
No. The C320KGS side-mount auxiliary contact is built for Eaton Freedom series starters and contactors in NEMA sizes 3 through 5 and IEC sizes L through S, and it mounts to that frame. The ABB CR305X series auxiliary contact is made for ABB contactors and relays, so it mates to a different device body. Use the CR305X only when the base device is ABB; for a Freedom starter, stay with the C320KGS.
4) What auxiliary contact reports circuit breaker status instead of starter status?
The Eaton C320KGS adds auxiliary switching circuits to a Freedom starter or contactor, so it follows the contactor's state. If you need breaker position or trip indication, the Square D ComPact NSXm auxiliary contact provides OF and SD circuit breaker status on NSXm breakers. Those are two different signals from two different devices, so pick based on what the control or SCADA circuit is monitoring.
5) I need a seal-in contact for a motor starter holding circuit. Is a 1NO auxiliary block enough?
For a straight three-wire seal-in around the start pushbutton, yes, C320KGS1 gives you the single normally open contact that does that job. If you also need to interlock another device or drive a run-indication or stopped-indication light, go to C320KGS3, which carries one NO and one NC in the same side-mount block.
6) Is this Eaton auxiliary contact listed for use in a commercial motor control center?
The C320KGS auxiliary contact is cUL Listed, which is what most commercial and industrial motor control installations call for on control components added to a starter panel.
7) Can I add this auxiliary contact to an existing starter already in service, or is it OEM only?
Both. It is a side-mount add-on block, so it goes onto Freedom starters and contactors already installed in a panel as easily as onto new OEM builds. Typical uses are motor control centers, adding auxiliary circuits to an existing contactor, and replacing a failed block on Freedom equipment already in the field.
8) I'm replacing a failed auxiliary block on an older Freedom starter. How do I order the matching one?
Match the Eaton part number stamped on the old block. The side-mount family here covers C320KGS1, C320KGS3, C320KGS5 and C320KGS22, all for NEMA 3-5 and IEC L-S frames. If the number is unreadable, count the poles and their states with the contactor de-energized: one NO is C320KGS1, one NO plus one NC is C320KGS3.
9) Is the Square D 9999SO4 alarm contact kit an equivalent to the Eaton C320KGS?
They are not interchangeable. The Square D 9999SO4 is a Type S isolated alarm contact kit, intended for Square D Type S equipment and an isolated alarm circuit. The Eaton C320KGS is a side-mount auxiliary contact for Eaton Freedom starters and contactors, offered in 1NO and 1NO-1NC circuit options. If the panel is Freedom equipment, order the C320KGS in the circuit option your control wiring calls for.
10) Do I need a Bussmann BAC auxiliary contact or an Eaton C320KGS for fuse status in a motor control center?
The Bussmann BAC series auxiliary contact is rated for a 1A to 12A amp range and is associated with Bussmann fuse equipment, so it is the choice when you are signaling from that hardware. The Eaton C320KGS mounts to the side of a Freedom starter or contactor in NEMA sizes 3 through 5 or IEC sizes L through S to add supplemental switching circuits to the starter itself. In a mixed MCC, both can appear in the same cubicle serving different signals.
