Schneider Electric CA2SK20U7 IEC Control Relay 2NO 240V AC 10A

SKU CH-32QM-W1VZT

IEC control relay with two normally-open contacts rated 10 A at 240 V AC, DIN-rail mount and screw-clamp terminals

  • Product typeIndustrial Electrical Controls & Automation
  • Product colorTransparent
  • 2NO contact form gives clean switching for control circuits
  • 10 A AC rating handles motor loads at 240 V
  • 2 A DC rating extends use to low-voltage panels
  • 5 VA coil consumption keeps panel power draw low
  • DIN-rail mount and screw clamps speed up installation

Compact DIN-rail control relay

The Schneider Electric CA2SK20U7 is a 240 V AC coil relay with two normally-open contacts rated at 10 A for switching lighting, heating or small motor loads in panels and machines. Its IEC style and screw-clamp terminals suit electricians and panel builders who need a slim, standards-compliant device for 50/60 Hz supplies.

Continuous-duty contact performance

Silver-nickel contacts carry the full 10 A at 120, 240, 480 or 600 V AC without derating during prolonged energisation, while the coil draws only 4.5 VA so multiple units can share a standard control transformer. DC switching is limited to 2 A at up to 600 V, so the relay is not suited for high-current DC circuits.

Thermal and installation profile

The relay operates up to 122 °F ambient with IP2X finger-safe terminals and a 2.19 in body depth that fits crowded DIN rails. No fan or forced airflow is required, and the low coil consumption keeps enclosure temperature rise minimal in normal cabinet installations.

Questions about this item

Does the relay produce noticeable heat or noise when powered continuously at 240 V AC?

The coil consumes 4.5 VA at 240 V AC and the maximum operating temperature is 122 °F, so heat rise is modest and the solid-state design runs silently.

What wiring and mounting hardware must already be in place to install this relay?

You need a DIN rail for mounting and screw-clamp terminals accept the conductors; the relay itself provides the IEC-style contact block.

Will the 2NO silver-nickel contacts switch legacy 120 V AC loads rated at 10 A without contact degradation?

Yes, the AC contact rating is 10 A at 120/240/480/600 V, so existing 120 V 10 A circuits are within the rated limits.
