Schneider Electric CA2KN40T7 4NO 480V AC 10A

The Schneider Electric CA2KN40T7 is an IEC control relay built for industrial automation panels. It provides four normally open contacts rated at 10 A for AC loads at 120, 240, 480 and 600 V. The coil operates on 480 V AC at 50/60 Hz and consumes 4.5 VA. Mounting options include DIN rail and surface fixing.

Who this suits and who should look elsewhere

This relay suits installers who need a compact 4NO contact block for 480 V AC control circuits in TeSys K compatible systems. It is not for circuits that require normally closed contacts, DC coil voltages, or contact ratings above 10 A AC or 2 A DC at the listed voltages. Buyers needing higher pole counts or different mounting styles should consider other models.

What to check before ordering

Verify that your control circuit supplies 480 V AC at 50 or 60 Hz to match the coil specification. Confirm the panel cut-out or DIN rail space accommodates the 1.77 in width, 2.28 in height and 2.24 in depth. Ensure the screw-clamp terminals suit your wire gauges and that the IP2X rating meets your enclosure protection requirements. Check the 122 °F maximum operating temperature against your cabinet ambient conditions.

Questions about this item

Does the relay need a 480V AC coil supply to operate?

Yes, the coil is rated for 480V AC at 50/60 Hz and draws 4.5 VA when energised.

Can the contacts switch the 120V and 240V circuits I already have in my panel?

The 4NO contacts are rated 10 A at 120V, 240V, 480V and 600V AC, so they will handle those voltages.

How can I confirm the relay is functioning after wiring it to the DIN rail?

Apply 480V AC to the coil; the four normally-open contacts should close and pass up to 10 A at the rated AC voltages.
