It carries four normally open instantaneous contacts and no built-in timing or make-before-break function. The screw and snap-on mounting lets you clip it directly onto a DIN rail or fasten it with screws, so it fits into a crowded enclosure without extra bracketry. The thermal current (Ith) is 0.8 to 1.1 A at 50 Hz and 0.85 to 1.1 A at 60 Hz — this is the continuous current the contact block can carry in free air, not the motor-load rating. For a control-circuit auxiliary, that's the number that governs heat rise in the panel.
The 45 mm width and 60 mm height match the standard S00 footprint, so it occupies one DIN-rail module position. Depth is 73 mm — enough clearance for the screw terminals and wiring. That's the standard for most control panels, not a special-case rating.
That figure tells you the silver-alloy contacts are designed for dry-circuit PLC inputs and low-current interlock signals, not just power switching.
Sourcing and fit confirmation
This part is specified into control panels as a standard SIRIUS auxiliary contactor. The 4 NO contact configuration, size S00 footprint, and screw-and-snap-on mounting are the key fit parameters for a BOM line.
