It belongs to the SIRIUS family (size S00), the compact frame used across Siemens motor-control portfolios for 45 mm wide devices. Rated operational current hits 10 A at AC-12 (resistive loads at 24 V), which covers most control-circuit switching for PLC outputs, relay coils, and indicator lamps.
The 45 mm width and 72 mm depth fit the standard S00 footprint — no extra clearance needed beyond the usual 57.5 mm height. Screw terminals accept solid conductors from 0.5 mm² up to 4 mm² (or AWG 20–12), covering typical control wiring. IP20 on the front means touch-safe when installed in a closed panel — standard for dry indoor environments.
Duty and environmental limits
Shock resistance is rated at 10 g for 5 ms and 5 g for 10 ms — enough for most industrial machinery but not for extreme vibration environments without additional damping. Contact reliability is specified as one incorrect switching operation per 100 million cycles at 17 V, 1 mA, which matters for low-energy signal circuits where oxide films or contamination can cause false opens. The part carries a reference code K per IEC 81346-2, used in system documentation for contactor/relay functions.
