Schneider Electric 8501JCK-23 Time Delay Relay

Schneider Electric's Square D 8501JCK-23 Time Delay Relay is a plug-in, off-delay timer that delivers a 0.6–60 second delay when operated from a 120 V AC coil. It plugs into the Square D 8501NR socket (an 11‑pin base), and UL-listed configurations are available when used with that socket. As part of the JCK timing relay family, the 8501JCK‑23 shares the same fixed timing window and plug-in form factor with other JCK models, and it is rated for up to 10 A of resistive load at the timing voltage. This 0.6–60 s range and plug-in 11‑pin base are documented across Schneider Electric’s JCK documentation and product catalogs. In practice, it enables timed control in automation sequences, such as interlocks, delayed activation, or staged start routines, using a compact timer in a standard control circuit. Variants in the JCK family, including off-delay timers like 9050JCK23V20, share the same timing range and 120 V coil options, and are commonly referenced in catalogs and distributor listings as compatible or interchangeable options within the same timing family.
