3RT2017-2BW42
The Siemens SIRIUS 3RT2017-2BW42, with its 48V DC special voltage coil and one set of normally closed auxiliary contacts, is suitable for replacing and upgrading existing equipment in 48V DC control power supply systems.
Product Positioning
The 3RT2017-2BW42 is a unique coil voltage variation model in this series, with a coil specification of 48V DC (uncommon 24V or 110V). Its operating range is 0.7~1.25 times the rated value, and it features one set of NC instantaneous auxiliary contacts. The main circuit maintains the standard S00 frame AC-3 12A, 400V/5.5kW specifications, making it suitable for existing systems or upgrades of specific industrial equipment whose power supply architecture itself uses 48V DC power.
Core Product Advantages and Features
48V DC special coil voltage
Unlike common 24V/110V coils, it is suitable for production lines or power distribution systems of communication/telecommunications related equipment where the original control power supply is 48V DC.
1 set of NC auxiliary contacts
Normally closed instantaneous contacts are easy to incorporate into interlocking protection or fault reporting circuit designs.
Spring-loaded terminals, lightweight body
Weighing approximately 0.308kg, the wiring terminals are screwless, making installation and subsequent maintenance more time-saving.
S00 standard framework compatibility
The shape and mounting hole positions are similar to those of the S00 contactor in the same series, making it easy to directly replace existing panels or to keep spare parts in a unified inventory.
