IEC Control Relay 4NO 120V AC

The Schneider Electric CA2KN40G7 is an IEC control relay with four normally open contacts rated at 10 A for AC loads up to 600 V. It operates from a 120 V AC coil consuming 4.5 VA and mounts on DIN rail or surface. The silver-nickel contacts are housed in a transparent body rated IP2X.

Upgrade from lower-contact-count relays

This relay replaces units that offer fewer than four normally open poles or lower AC contact ratings at 120 V, 240 V, 480 V and 600 V. The jump is worth it when a single device must switch multiple circuits at 10 A without adding extra relays to the panel.

Suits panels needing four NO poles at 10 A

It suits control panels that require four normally open contacts at 10 A with screw-clamp wiring and DIN-rail mounting. Buyers who need changeover contacts, DC coil operation or a higher IP rating should look at something else.

Questions about this item

What mounting options does the 1.77 in wide relay body support?

The relay body mounts on DIN rail and can also be surface mounted using the integral screw-clamp terminals.

What wiring step is often missed when connecting the 120V AC coil to the screw-clamp terminals?

The coil terminals must be wired to the 120V AC supply at 50/60 Hz; forgetting to match the 4.5 VA coil rating can cause overheating.

When should the silver-nickel contacts be inspected given the 10 A AC rating at 120/240/480/600V?

Inspect contacts after high-cycle operation or if the 122 °F maximum operating temperature is regularly approached, as contact wear increases under sustained load.
