It's built for control-circuit switching inside motor starter assemblies or as a signal repeater in larger panels. The 10 A rating at 24 V covers most PLC-level loads; at 230 V it still handles 6 A, and at 690 V it's good for 1 A. That derating curve is what you'd expect from a contactor this size — the AC-15/DC-13 application matters more than the raw number.
Screw and snap-on mounting onto DIN rail — the 45 mm width means it takes up a single modular device slot. The S00 footprint is standard across the SIRIUS contactor range, so it shares the same panel layout as the 3RT2 contactors. That's useful when you're squeezing it into a tight sub-panel or orienting it for wireway access.
Contact reliability and surge suppression
Contact reliability is spec'd at one incorrect switching operation per 100 million cycles at 17 V, 1 mA — that's the low-energy dry circuit case where oxide films matter. If you're switching PLC inputs or logic-level signals, this contactor won't give you intermittent opens. The built-in varistor surge suppressor across the coil handles the inductive kickback; no external diode or RC snubber needed for standard AC coils.
Shock resistance is 10 g at 5 ms and 5 g at 10 ms — adequate for most industrial machinery but not rated for sustained vibration near a crusher or press. Wire termination accepts 0.25 to 2.5 mm² solid or stranded; the 114 mm depth leaves room for the wire bend radius inside a standard 200 mm deep enclosure.
