    AI Overview
    The Siemens SIRIUS 3RW4426-3BC44 is a high-feature, solid-state soft starter designed for smooth starting and stopping of three-phase asynchronous motors, rated for 77 A and 37 kW at 400V (200-480V AC). It features internal bridging contacts, innovative torque control, and spring-type terminals, making it suitable for demanding applications, with a preferred successor being the 3RW5526-3HA14. 
    Key Specifications & Features: 
    • Power & Current: 37 kW (at 400V) / 77 A nominal.
    • Voltage Range: 200-480 V AC, 50/60 Hz.
    • Control Voltage: 115-230 V AC.
    • Circuit Types: Suitable for inline (up to 77 A) and inside-delta circuits (up to 133 A).
    • Terminals: Spring-type.
    • Functions: Soft start, soft stop, torque control, adjustable current limiting, and integrated motor overload/device protection.
    • Applications: Ideal for heavy-duty starting (e.g., pumps, fans, compressors) to reduce mechanical stress and power system fluctuations.
    • Successor: Siemens indicates the SIRIUS 3RW5526-3HA14 is the preferred replacement. 
    Documentation & Purchasing: 
    • Manual: Detailed configurations, installation, and troubleshooting can be found in the Siemens 3RW44 Manual.
    • Availability: New units are available through specialized industrial suppliers and platforms, often listed with, for example, WiAutomation or eBay.
