Siemens Industrial Controls 49SAS01 Selector Switch
Field-ready and engineered for industrial-grade control, the Siemens 49SAS01 Selector Switch is a critical component for managing HVAC systems, motor starters, and automation panels. This 3-position Hand-Off-Auto (H-O-A) selector switch features an A3 configuration, providing the essential manual-to-automatic override required for troubleshooting and system testing. Built with a chrome-plated metal front ring and a durable white-on-black short lever actuator, this 30mm pilot device is designed to withstand harsh shop environments with an operational temperature range of 31°F to 158°F.
The Siemens 49SAS01 is a flush-mount unit compatible with NEMA 1, 3, 3R, 4, 4X, 12, and 13 enclosures. It comes pre-equipped as a heavy-duty assembly including the selector switch base, an A600/P600 rated contact block, and a standard legend plate. Whether you are integrating it into a Class 14 or Class 40 motor starter or a custom lighting control panel, this switch ensures positive action indexing and long-term mechanical reliability in demanding industrial control systems.
Key Benefits for Technicians:- NEMA Versatility: Fully rated for high-exposure environments, including NEMA 4X wash-down and NEMA 12/13 oil-tight applications.
- Prewired Efficiency: Supplied with prewired NO/NC contact blocks to reduce installation time in the field.
- Robust Load Handling: Rated for use with lighting and motor control circuits from 20 to 400 Amps.
- Standardized Fit: Fits standard 30mm mounting holes, making it a direct drop-in replacement for most industrial panels.
Can I change the color of the selector lever?
Yes, while it comes standard with a white insert, the lever is designed to accept different color inserts available from the Siemens Class 52 pilot device line.
What is the difference between the positions on this HOA switch?
The 'Hand' position provides manual override to the 'On' state, 'Off' disconnects the circuit, and 'Auto' allows for remote control via thermostats, pressure switches, or PLCs.
Is this switch suitable for outdoor use?
Yes, when mounted in a properly rated NEMA 3R or 4X enclosure, the 49SAS01 maintains its environmental integrity against rain and corrosion.
