Sylvania Joslyn Clark KTM-10 Auxiliary Contact

KTM-10 is a normally open auxiliary contact kit for Joslyn Clark Sylvania TM-series air-break (NEMA) contactors. Labeled as the KTM-10 N.O. AUX. KIT, it is designed to attach to JC14 interfaces on contactors sized 00 through 4, providing a single NO auxiliary contact that signals contactor status to control circuits and interlocks without carrying the main load. Variants exist with suffixes KTM-10-A through KTM-10-Z, and the part is cross-referenced by suppliers as KTM10 and 4052CD. The kit is manufactured by Danaher Controls/Joslyn Clark (Sylvania), and distributor listings show a weight of about 0.09 kg. Availability is documented across Radwell and Santa Clara Systems, underscoring its role as the standard NO auxiliary accessory for TM-series contactors.
