  • Low 4.5 VA coil consumption reduces control-circuit power draw

Industrial IEC Control Relay

The Schneider Electric CA2KN22G7 is a 120 V AC coil relay rated for 10 A on AC contacts and 2 A on DC contacts. It provides two normally open and two normally closed poles for switching control circuits in panels and machinery. The unit mounts on DIN rail or directly on a surface and uses screw-clamp terminals for secure wiring. Its IP2X rating protects against finger contact with live parts.

Sustained Operation Characteristics

The relay consumes 4.5 VA while energised and is rated for a maximum operating temperature of 122 degrees Fahrenheit. Contacts maintain their 10 A AC rating at 120, 240, 480 and 600 V as well as 2 A DC at 125, 250 and 600 V across 50 or 60 Hz supplies. The compact body measures 1.77 inches wide by 2.24 inches deep by 2.28 inches high, allowing dense packing in cabinets without derating.

Upgrade Path and Fit

This relay replaces older IEC-style control relays that use the same coil voltage and contact arrangement but lack the TeSys K series compatibility. The jump is worthwhile when a panel design requires the standardised mounting footprint and screw-clamp connections of the TeSys K family. It is not suited for applications needing higher contact counts, different coil voltages or solid-state switching.

Questions about this item

How much heat does the 120 V AC coil generate during continuous operation?

The coil draws 4.5 VA at 50/60 Hz, which is a low power dissipation that will not raise the enclosure temperature significantly under normal conditions.

What wiring and mounting hardware must I supply to install the relay?

You need stranded or solid wire sized for 10 A, a screwdriver for the screw-clamp terminals, and a standard DIN rail or surface-mount screws for the mounting style shown.

Will the 10 A AC contacts switch reliably alongside my existing 120 V control circuit?

Yes, the contacts are rated 10 A at 120/240/480/600 V AC and the coil operates on 120 V AC at 50/60 Hz, so they match common 120 V control voltages directly.
