Schneider Electric 9050 JCK17V20 NSNBC01 Relay

Schneider Electric's Square D 9050JCK17V20 NSNBC01 is a plug-in timing relay (Type JCK) in the 9050 series, delivering on-delay timing with a DPDT contact arrangement of 2 normally open and 2 normally closed contacts. It plugs into a compatible 8501NR relay socket (such as 8501NR51 or 8501NR52) and is UL-listed when used with the proper socket, with CSA certification. The package uses an 8-pin tubular plug-in form factor and is designed to switch loads up to 10 A resistive at 120/240 VAC and 30 VDC, 3 A inductive at 120/240 VAC, with NO contacts rated up to 1/2 HP and NC contacts up to 1/3 HP at the same voltages; the timer is powered from 120 VAC / 110 VDC. This 9050JCK timing relay from Square D is commonly used in industrial control applications for sequencing and delayed switching in control circuits.
