It packs a set of 10 units and uses diode technology to quench inductive voltage spikes across the control circuit coil, protecting adjacent electronics. Rated for control circuit voltages from 24 to 250 V DC, this module covers a wide span of common DC coil supplies used in industrial panels. The operating temperature range is -4 to 122 °F (-20 to 50 °C), with storage allowed down to -58 °F (-50 °C). The LA4SKC1U is classified as obsolete by the manufacturer. There is no documented direct replacement or official last-time-buy part number; any substitution must be validated against the contactor's coil voltage and mounting interface. The module is sourced to order; a confirmed RFQ with target quantity and lead time will determine availability. ## Key Specifications in Procurement Context The part is a single unit per package, sold as a set of 10, which means ordering one line item supplies ten modules. The suppressor technology is diodes only — no varistor or RC network — so it is suited for DC coils where polarity is fixed and a freewheeling path is acceptable. Maximum peak voltage is specified as 1 Uc, meaning the diode clamps at approximately the control circuit voltage; no additional voltage margin above the coil rating. Verify the contactor's coil voltage falls within the 24–250 V DC range before committing the order.","metaTitle":"LA4SKC1U Suppressor Module, Obsolete Sourcing","metaDescription":"Obsolete SQUARE D LA4SKC1U diode suppressor module for TeSys contactors, 24-250 V DC.
