Industrial IEC control relay

The Schneider Electric CA2KN22B7 is an IEC-style control relay rated at 10 A with a 24 V AC coil. It provides two normally open and two normally closed contacts for switching AC loads up to 600 V or DC loads up to 600 V at 2 A. The unit mounts on DIN rail or a flat surface using screw-clamp terminals.

Suited for panels needing four-pole switching

This relay fits panels that require 2NO/2NC contact arrangement and 24 V AC coil control. It is not for circuits demanding a different coil voltage or a contact count other than four poles. Installations needing IP20 finger-safe terminals or a specific approval not listed should verify compatibility first.

24 V AC coil voltage decides fit

The coil operates on 24 V AC at 50/60 Hz and draws 4.5 VA. If the control circuit supplies a different voltage or frequency the relay will not function correctly. All other ratings depend on this coil specification being met.

Questions about this item

Should I pick the 2NO/2NC contact form or a different configuration for my control circuit?

The CA2KN22B7 provides two normally open and two normally closed contacts in one relay, so a single unit can handle both make and break functions without adding extra relays.

What does the 10 A AC contact rating mean when the relay is installed in a panel?

It means each contact can switch up to 10 A at 120, 240, 480 or 600 V AC, but only 2 A at the same voltages DC, so size your load and wiring for the lower DC figure if the circuit is not purely AC.

The coil is 24 V AC at 50/60 Hz — what does that cap in practice?

The coil draws 4.5 VA, so your 24 V AC supply must deliver that apparent power continuously; the relay will operate reliably at either 50 Hz or 60 Hz mains frequency.
