Industrial Control Relay

The Schneider Electric CA2SK20B7 is an IEC control relay designed for DIN rail mounting in electrical panels. It operates on a 24V AC coil and provides two normally open contacts rated at 10 A for AC loads and 2 A for DC loads. The unit uses screw clamp terminals and carries an IP2X protection rating.

Panel Builders and Maintenance Teams

This relay suits installers wiring motor starters, lighting circuits or small heating loads that need a compact IEC-style contact block. It is not intended for buyers who need additional contact configurations such as normally closed poles or higher coil voltages. The fixed 2NO layout and 24V AC coil limit flexibility for other control voltages.

10 A AC Contact Rating

The decisive figure is the 10 A AC rating at up to 600 V, which determines whether the relay can switch the intended load. The 2 A DC rating at 125 V, 250 V or 600 V covers low voltage control circuits. Power consumption is 4.5 VA at 50/60 Hz and the maximum operating temperature is 122 degrees F.

Questions about this item

What comes in the box and do I need to buy a DIN-rail clip or wiring ferrules separately?

The relay ships as a single unit with screw-clamp terminals ready for wire insertion; DIN-rail mounting is integral, so no separate clip is required, and ferrules are optional depending on your wiring practice.

Should I choose the 24 V AC coil or a different voltage for a 50/60 Hz panel?

This model is only offered with a 24 V AC coil rated for 50/60 Hz operation; select it when your control circuit supplies 24 V AC at either frequency.

Will the 10 A AC contact rating hold at 240 V in a motor starter circuit?

Yes, the silver-nickel contacts are rated 10 A at 240 V AC (also 120/480/600 V AC) and 2 A at 125/250/600 V DC, with a 4.5 VA coil burden.
