Schneider Electric CA2KN22U7 IEC Control Relay

The Schneider Electric CA2KN22U7 is an IEC control relay built for industrial automation and electrical control panels. It provides reliable switching for circuits up to 10 amperes at 240 volts AC. The unit mounts on DIN rail or a flat surface and uses screw clamp terminals for secure wiring.

2NO/2NC contact form with 10 A AC rating

This relay features a 2NO/2NC contact configuration rated at 10 amperes for 120, 240, 480 and 600 volts AC. The coil operates on 240 volts AC at 50 or 60 hertz and draws 4.5 volt-amperes. DC contact rating is 2 amperes at 125, 250 and 600 volts DC. Maximum operating temperature is 122 degrees Fahrenheit.

Suited for panels needing four-pole switching

Electricians and panel builders who need a compact four-pole relay with screw terminals and DIN rail mounting will find this model fits standard TeSys K cut-outs. It is not for applications requiring higher current ratings, different coil voltages or plug-in base connections. Buyers needing sealed enclosures beyond IP2X should look at other designs.

Questions about this item

What does the 10 A AC contact rating mean when the relay is installed in a control panel?

It means each contact set can switch up to 10 amps at 120, 240, 480 or 600 V AC, so the relay can directly control motors, heaters or contactors within those limits.

How does the screw-clamp connection affect the maximum wire size I can use?

The screw-clamp terminals accept solid or stranded conductors tightened by screw; the relay's 10 A rating and IP2X protection apply when wires are secured to the manufacturer's recommended torque.

What space do I need on the DIN rail for the 1.77 in wide body?

The relay is 1.77 in wide, 2.28 in high and 2.24 in deep, so allow at least that width on the rail plus clearance for wiring and the 4.5 VA coil heat dissipation.
