CIT Relay and Switch J115F31AL120VACS Power Relay

This power relay features a single-pole, single-throw (SPST) normally open (N.O.) contact configuration with quick connect terminals, designed for robust industrial applications. Operating at 120 VAC coil voltage, it supports a current capacity of up to 40 A and has a low-profile, sealed body for enhanced durability and environmental resistance. The relay uses silver tin oxide (AgSnO2) contact material for reliable switching, long lifespan, and resistance to corrosion. It consumes approximately 2 VA of coil power, suitable for automation and control systems requiring high current switching with space-efficient design.
