It carries 3 instantaneous normally-open contacts and is sized S00, meaning it mates directly with the S00 contactor family (e.g., 3RT1015, 3RT1016, 3RT1017) for mirroring or extending auxiliary contact sets on a DIN rail. At 45 mm wide and 72 mm deep, it occupies a single DIN-rail slot alongside its parent contactor. The screw and snap-on mounting lets you clip it onto the rail or onto the contactor's side without tools — common for panel builders wiring control circuits.
Pollution degree 3 means this contactor is rated for environments where conductive dust settles on the terminals — exactly what a cement plant control room sees. The IP20 front keeps fingers and tools out but does not seal against airborne grit; the enclosure around the panel provides that seal. Storage and transport range -55 to +80 °C means it survives a hot truck or warehouse without degrading. Shock resistance 10g / 5 ms and 5g / 10 ms is enough for normal machine vibration and handling drops. Contact reliability is rated at one incorrect switching operation per 100 million cycles at 17 V and 1 mA — that is the dry-circuit limit. For PLC-level signals (24 VDC, 10 A rated at 24 V), this contactor switches reliably without gold-plating.
Wiring and mounting notes
Terminals accept solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². No leading or delayed switching action — all three contacts close simultaneously.
