Schneider Electric CA3SK11BD control relay 24V DC 10A 1NO/1NC

SKU CH-VSWD-MJ66T

An IEC control relay with 1NO/1NC contacts rated 10 A AC, 24 V DC coil, DIN-rail mount and screw-clamp terminals

  • TypeIndustrial Electrical Controls & Automation
  • ColorTransparent
  • Reliable switching for 10 A AC loads at up to 600 V
  • Low 24 V DC coil voltage reduces control-circuit risk
  • Compact 1.06 in width fits dense DIN rail layouts
  • Silver-nickel contacts resist wear for long service life
  • IP2X finger-safe terminals protect installers during maintenance

Compact IEC control relay for 24 V DC panels

This Schneider Electric CA3SK11BD relay switches loads up to 10 A on AC circuits and 2 A on DC circuits. It uses a single normally-open and normally-closed contact pair in a 1.06 in wide DIN-rail housing. The coil draws 2.2 W at 24 V DC for low standby consumption.

Check coil voltage and contact ratings before wiring

Verify that your control circuit supplies exactly 24 V DC to match the coil specification. Confirm the load does not exceed 10 A at 120–600 V AC or 2 A at 125–600 V DC. Ensure the DIN rail spacing accommodates the 2.19 in depth and 2.2 in height of the unit.

Suits panels needing one change-over contact

Ideal for machine builders adding a single interlock or status signal in a TeSys SK series assembly. Not suited for applications requiring multiple poles, higher DC breaking capacity, or coil voltages other than 24 V DC.

Questions about this item

Does the CA3SK11BD relay arrive with mounting hardware or do I need to buy DIN rail clips separately?

The relay is designed for DIN rail mounting and has screw-clamp terminals ready for wiring; rails and end clamps are not included and must be sourced separately.

Should I choose the 24 V DC coil version or is there an AC coil alternative in this series?

This specific model operates on a 24 V DC coil; other coil voltages exist in the TeSys SK range but are different part numbers.

What does the 10 A contact rating mean when the relay is switching a 240 V AC load in my panel?

The contacts are rated for 10 A at 240 V AC, so they can carry that current continuously within the 122 °F maximum operating temperature.
