Siemens Industrial Controls 3RT2025-1AM20 Contactor
The Siemens 3RT2025-1AM20 is a heavy-duty SIRIUS series power contactor engineered for motor control and switching resistive or inductive loads in industrial HVACR systems. This size S0 contactor features a 3-pole configuration with a 17A rating (AC-3) and is equipped with a 208V AC 50/60Hz coil. Built for high-frequency switching and long-term reliability in the field, this unit provides a primary power solution for 3-phase motors up to 7.5 kW at 400V, or 10 HP at 460V. The 3RT2025-1AM20 includes integrated auxiliary contacts (1 NO + 1 NC) and utilizes screw terminals for secure, vibration-resistant wiring. Its DIN rail mounting design ensures quick installation and seamless compatibility as a modern replacement for the legacy 3RT1025-1AM20 series.
Key Benefits for Contractors:- High Performance: Rated for 17A and 3-phase loads, making it ideal for standard motor control applications.
- Universal Compatibility: Fits standard 35mm DIN rails and integrates easily into Siemens SIRIUS motor starters.
- Field Reliability: Enhanced auxiliary contact stability for electronic circuits and standard HVACR control logic.
- Compact Footprint: The Size S0 frame saves critical cabinet space while managing high-amperage switching.
- Is the 3RT2025-1AM20 a direct replacement for the 3RT1025-1AM20? Yes, it is the dimensional and electrical successor; however, note that some direct-mount accessories from the older series may require updating.
- Can this contactor be used with 50Hz and 60Hz systems? Yes, the 208V AC coil is designed for dual-frequency operation (50/60Hz).
- What is the maximum horsepower rating for this 17A contactor? Professionals typically use this unit for 10 HP at 460V or 5 HP at 230V in 3-phase systems.
