Solid-state direct starter with AS-Interface bus integration
The 3RK4320-5JQ64-0BA2: It is designed for AS-Interface bus communication, supporting the AS-Interface protocol for control and diagnostics. The unit operates on a 340–460 V AC supply (50/60 Hz) and draws its control power from a 20.4–26.4 V DC rail. Two onboard digital inputs are available for local sensing or pushbutton wiring.
Envelope and mounting flexibility for panel integration
The housing measures 205 mm deep, 290 mm wide, and 215 mm high — a footprint that occupies a standard panel cutout. The IP54 rating means it is protected against dust ingress and splashing water, suitable for enclosure mounting in industrial environments without additional sealing. The operating ambient temperature range of –25 to +50 °C covers most indoor industrial installations; no derating is required within that band for the listed ratings.
Active lifecycle and procurement posture
The reference code per IEC 81346-2 is Q, for power circuit equipment.
