205 x 245 x 215 mm — panel space and mounting
The 3RK4320-3LQ51-1BA3: The 205 mm depth, 245 mm width, and 215 mm height define the envelope for DIN-rail or screw-mount installation.
6.3 A AC-3 at 400 V — motor duty and trip class
The Class 10 bimetal overload clears within 10 seconds at 600% of set current, which keeps the motor winding below its thermal limit on a jammed conveyor or stalled pump.
AS-Interface bus with 2 DI and brake control
The unit speaks AS-Interface natively — no gateway or coupler needed between the starter and the AS-i network. Two digital inputs handle limit switches or pushbuttons locally, and the 400 V AC brake output directly drives a motor brake coil without an interposing relay. Control supply is 20.4-26.4 V DC, drawn from the AS-i power supply or a separate 24 V rail.
Current production — quoted to order
Lifecycle stage is current — Siemens still manufactures this reversing starter, so it's not a legacy scavenger hunt.
