Spec SheetThe Square D Type JCK plug-in timer is engineered to deliver precise timing control in industrial automation. It features an on delay mode, initiating a delay when voltage is applied, with relay contacts switching after 30 seconds. When voltage is removed, contacts revert to their default state.
This timer is rated for 10 amperes resistive at 120 VAC and 240 VAC, and 3 amperes inductive at the same voltages. It operates on 120 VAC or 110 VDC power supply and is compatible with relay sockets 8501NR51 or 8501NR52, which can be mounted on a 35 mm DIN track or directly on a panel. The timer's contacts are DPDT with a tubular pin shape, rated for 1/3 HP on NC contacts and 1/2 HP on NO contacts at 120 VAC and 240 VAC.
UL listed when used with the appropriate relay socket, UL recognized, and CSA certified, this timer is suitable for commercial and industrial applications requiring reliable timing control.
