Product details

It is rated for 22 kW at 400 V in AC-2 duty (slip-ring motor starting) and 41 A at 400 V in AC-4 duty (plugging/inching), which defines its capability for demanding motor applications with high electrical wear.

The 690 V rating of 11.4 kW confirms it can handle higher-voltage distribution systems, though at reduced power. Auxiliary contact ratings cover 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — enough for pilot duty on small relays or PLC inputs, but not for main power. The switching frequency limits of 800 cycles/hour in AC-3 and 300 cycles/hour in AC-4 set the thermal ceiling for repetitive switching; exceed these and the contactor rises above its rated temperature. The IP20 rating on the front protects against finger contact; the IP00 terminal area means the connection points are exposed and require enclosure protection in the panel.

Mounting and Termination

Side-by-side mounting is permitted, which lets you pack multiple contactors without dead space, but derating for thermal accumulation should be verified per the manufacturer's guidelines. The auxiliary terminals accept 2x 0.5 to 1.5 mm² solid or 2x 0.75 to 2.5 mm² stranded. This covers common panel wire sizes from 18 AWG to 4 AWG, but verify lug compatibility for larger stranded conductors.

Shock resistance is 15 g for 5 ms and 8 g for 10 ms under AC operation, with DC operating time of 20 to 25 ms and arcing time of 10 to 15 ms. These figures matter for applications near heavy machinery or conveyors where vibration could cause contact bounce.

Compliance documentation includes RoHS substance prohibition dated May 1, 2012, covering the initial EU RoHS directive. REACH, UL, and IEC certifications are standard for the SIRIUS family, though specific cert numbers should be verified against the nameplate or manufacturer's declaration.

Frequently asked questions

What are the key dimensions for panel layout?

The contactor has a width of 55 mm, height of 112 mm, and depth of 164 mm. It mounts on a 35 mm DIN rail per DIN EN 50022, and side-by-side mounting is permitted.

What wire sizes does the contactor accept?

Main circuit screw terminals accept solid conductors up to 2x 4 mm² and stranded up to 2x 25 mm². Auxiliary terminals accept 2x 0.5 to 1.5 mm² solid or 2x 0.75 to 2.5 mm² stranded.

What is the AC-4 current rating and why does it matter?

The AC-4 rating at 400 V is 41 A. AC-4 duty covers plugging and inching — the most severe switching condition for a contactor because the motor is already spinning when the contacts close. This rating governs electrical contact life in reversing or jogging applications.

What compliance documentation is available?

RoHS compliance is documented with a substance prohibition date of May 1, 2012. Standard certifications for the SIRIUS family include CE, UL, and CSA, though specific certificate numbers should be confirmed from the manufacturer's documentation portal.
