It provides 4 normally-open instantaneous contacts for switching control circuits, signal interlocking, or extending the contact count on a main contactor or starter. Contact reliability is rated at one incorrect switching operation per 100 million cycles at 17 V, 1 mA — meaning it can be trusted for dry-contact PLC inputs where low-level switching is critical.
Mounts via screw or snap-on to DIN rail. The S00 footprint is 45 mm wide, 57.5 mm tall, 72 mm deep — standard for this frame size, so it fits existing S00 layouts without panel rework. This helps when fitting into crowded enclosures or angled subpanels. Front protection is IP20 — finger-safe for the panel face but not sealed; keep it inside a cabinet away from washdown or dust.
Terminals accept solid conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm². This covers standard control wiring from signal-level pairs up to 4 mm² for heavier pilot circuits.
Shock rated at 10g / 5 ms and 5g / 10 ms — robust enough for machine-mounted applications with vibration. RoHS compliance date listed as July 1, 2006, confirming it meets the EU substance restrictions.
