Rated for 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V, the contacts handle typical PLC and relay loads across common control voltages. The 6 kV rated surge voltage resistance means it can be used in circuits with overvoltage category III without additional suppression on the contact gap. The 4 NO contact arrangement makes it a direct fit for applications needing a set of isolated auxiliary contacts — adding feedback signals, interlocking, or status indication to a contactor or motor starter.
The S00 frame size (45 x 57.5 x 111 mm) matches the same mechanical envelope as the 3RT2 S00 contactor series, so the auxiliary block clips directly onto the contactor or sits beside it with shared DIN rail space. Terminals accept solid or ferruled stranded conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm² — enough for daisy-chaining control wiring through the same clamp.
Rated for operation from -25 to +60 °C and storage/transport from -55 to +80 °C, with 10g/5 ms and 5g/10 ms shock resistance — suitable for industrial panels subject to vibration. RoHS compliance date is July 1, 2006, and pollution degree 3 rating means it tolerates conductive pollution in controlled environments (typical for industrial control panels).
