Operation

These DC coil kits have separate pick-up and seal windings. A special (side mounted) early-break NCI auxiliary contact is used to either disconnect the pick-up winding or insert the seal winding in series with the pick-up winding, depending on the frame size of the contactor. DC coil kits come in two styles, a suffix 1 and a suffix 4. Suffix 1 contains only the special (side mounted) early break NCI auxiliary contact. Suffix 4 contains a NO contact in the same package as the special (side mounted) early-break NCI auxiliary contact. 

Note: For NEMA Sizes 00 and 0 and IEC Sizes A–F, contactors may utilize either suffix 1 or 4 DC coil kits; starters may utilize suffix 4 DC coil kits only. For NEMA Sizes 1 and 2 and IEC Sizes G–K, both contactors and starters may utilize a suffix 4 DC coil kit only. 

On the above sizes only, when the special auxiliary package is mounted on the side of a contactor or starter, no standard auxiliary contact may be mounted on the same side.

Note: For NEMA Sizes 3–5 and IEC Sizes L–S, special coil NCI clearing contact is an add-on auxiliary (must mount on a base mount auxiliary contact; normally a 1NO). This arrangement will normally account for two of the three contact positions on the side of each contactor or starter.
