Panel fit and mounting flexibility
The 3RK4320-3MQ51-0BA2: Dimensions are 205 mm deep, 245 mm wide, and 215 mm high — the width is the dimension that drives enclosure fill on a DIN-rail layout. IP54 protection means it handles dust and splashing water — fine for panel-mount in industrial enclosures but not for direct washdown zones.
AS-Interface integration and I/O
This starter communicates over AS-Interface protocol — no PROFIBUS or PROFINET onboard, so it belongs on an AS-i network segment, not a higher-level fieldbus directly. It includes 2 digital inputs for local sensors or limit switches, and a motor brake output component for holding brakes on vertical-axis drives. Short-circuit protection is handled by upstream circuit breakers — the starter itself provides the overload protection via the bimetal relay.
Lifecycle and compliance
Substance prohibition date of 05/01/2012 aligns with RoHS compliance — the starter meets the EU RoHS directive for restricted substances. Reference code per IEC 81346-2 is Q, classifying it as a switching device in the system documentation.
