Transparent IEC control relay with screw-clamp terminals for DIN rail mounting

Schneider Electric

Schneider Electric CA2KN40B7 IEC Control Relay 4NO 24V AC 10A

SKU CH-WAKA-YX8BD

IEC control relay with four normally-open contacts, 10 A AC rating, 24 V AC coil and DIN-rail or surface mounting

  • TypeIndustrial Electrical Controls & Automation
  • ColorTransparent
  • 4NO contact form gives four normally-open circuits
  • 24 V AC coil voltage suits common control voltages
  • 10 A AC contact rating handles substantial loads
  • 5 VA power consumption keeps energy draw low
  • DIN rail and surface mounting offers flexible installation

IEC control relay for DIN-rail panels

This Schneider Electric CA2KN40B7 relay provides four normally-open contacts rated at 10 A for 120 to 600 V AC circuits. It operates from a 24 V AC coil drawing 4.5 VA at 50 or 60 Hz and mounts on standard DIN rails or flat surfaces inside electrical enclosures.

Fits into control cabinets with screw-clamp wiring

The relay body measures 1.77 in wide by 2.28 in high by 2.24 in deep and uses screw-clamp terminals for secure conductor attachment. Its IP2X rating protects against finger contact while leaving ventilation open for adjacent components in the panel.

Handles sustained 10 A AC loads at up to 122 °F

Silver-nickel contacts maintain the full 10 A rating across 120, 240, 480 and 600 V AC without derating at the maximum operating temperature. DC switching is limited to 2 A at 125 to 600 V, so the relay is intended for continuous AC control duty rather than high-current DC applications.

Questions about this item

Will the 10 A AC contact rating hold up under continuous load without overheating?

The relay is rated for 10 A at 120/240/480/600 V AC and has a maximum operating temperature of 122 °F, so sustained operation within those limits is supported by the design.

How much heat and noise does the 24 V AC coil produce during all-day operation?

The coil consumes 4.5 VA at 50/60 Hz, which typically results in low heat and silent operation with no moving parts that generate audible noise.

What mounting hardware do I already need to install this relay?

It is designed for DIN rail and surface mounting using screw-clamp terminals, so you need a compatible DIN rail or a flat surface with screws for fixing.
