Schneider Electric CA2SK11B7 IEC Control Relay 1NO/1NC 24V AC 10A video accessory

SKU CH-KKHP-9W1M4

IEC control relay with 1NO/1NC contacts, 24V AC coil and 10A AC rating for DIN-rail mounting

  • TypeIndustrial Electrical Controls & Automation
  • ColorTransparent
  • IEC-standard relay integrates with TeSys SK systems
  • 10 A AC switching handles 120–600 V loads
  • 24 V AC coil suits common control voltages

  • IP2X finger-safe housing rated to 122 °F

Schneider Electric CA2SK11B7 IEC Control Relay

This new IEC control relay provides a 10 A contact rating with a 1NO/1NC contact form. It operates on a 24V AC coil voltage at 50/60 Hz and mounts on a DIN rail using screw clamp connections. The unit has an IP2X rating and a maximum operating temperature of 122 degrees F.

Suitability for switching and automation tasks

It suits installers needing a compact relay for AC or DC control circuits within the specified voltage and current limits. The silver nickel contacts support 10 A at up to 600V AC and 2 A at up to 600V DC. It is not for applications requiring higher current capacity, different coil voltages, or alternative mounting styles.

24V AC coil voltage decides compatibility

The coil requires a 24V AC supply at 50/60 Hz, consuming 4.5 VA. This single voltage rating determines whether the relay matches the control circuit. Verify the supply voltage before purchase.

Questions about this item

Does this relay need a DIN rail already fitted in the panel for mounting?

Yes, the relay uses DIN rail mounting, so a standard DIN rail must be present in the enclosure before installation.

Can the 24 V AC coil operate on both 50 Hz and 60 Hz supplies?

The coil is rated for 50/60 Hz, so it works on either frequency without modification.

How can I verify the contacts are switching correctly after wiring?

Apply 24 V AC to the coil and measure continuity across the normally-open and normally-closed contacts; they should change state cleanly at 10 A AC rating.
