SIRIUS reversing starter for AS-Interface lines
Rated 1.6 A at AC-3 duty on 400 V, it switches reversing motor loads up to that current — the Class 10 bimetal overload relay ensures rapid trip under locked-rotor conditions, protecting the motor winding before thermal damage sets in. Two digital inputs are available for local control signals; the unit accepts a 340...440 V operating voltage and draws its control supply from a 20.4...26.4 V DC source.
Bus integration and mounting
AS-Interface is the onboard protocol — no PROFIBUS or PROFINET variant here. The bus connection handles parameterization and status feedback, reducing point-to-point wiring in the panel. The IP54 rating means it's protected against dust ingress and splashing water — suitable for floor-level cabinet placement near washdown zones. Dimensions are 245 mm wide, 205 mm deep, 215 mm high. Account for the 205 mm depth when routing AS-Interface cables and motor leads behind the unit on the DIN rail.
It is a reversing starter with integrated brake control output — a specific combination that makes direct substitution with a standard contactor block non-trivial. No official replacement order code has been published, so the BOM line stays with this MPN.
