It is designed to extend the signal-routing capacity of a main contactor or to serve as a standalone interposing relay in a control circuit. The contact reliability spec — one incorrect switching operation per 100 million cycles at 17 V, 1 mA — means it also reliably switches low-energy signals from sensors or electronic modules, not just power-level loads.
Dimensions are 45 mm wide, 57.5 mm high, and 72 mm deep — the standard S00 footprint that fits alongside SIRIUS contactors and overload relays on the same rail. The IP20 front protection means it is touch-safe for the panel interior but not rated for washdown.
For compliance documentation, the substance prohibitance date of 07/01/2006 aligns with the original EU RoHS directive, so the part is RoHS-compliant. The SIRIUS series carries CE and UL/CSA certifications as standard, though specific approval marks are not itemized in this listing.
Shock resistance is 10g for 5 ms and 5g for 10 ms, which covers most industrial vibration profiles without special mounting. Mechanical endurance is 30 million operating cycles typical for the contactor size, and the contact reliability figure of 100 million operations at low level (17 V, 1 mA) confirms it can handle dry switching without contact oxidation issues.
