Siemens Industrial Controls 3RT2025-1AK60 Contactor

The Siemens SIRIUS 3RT2025-1AK60 is a heavy-duty, S0 size power contactor engineered for demanding industrial motor control systems. Designed as a 3-pole IEC contactor, this unit handles up to 17A at 400V (AC-3e/AC-3), delivering 7.5kW of switching power for fans, pumps, and compressors. The 120V AC coil (60Hz) is optimized for standard control circuits, while the integrated 1NO/1NC auxiliary contacts provide immediate feedback for status monitoring or safety interlocking. Built with screw terminals for secure, vibration-resistant wiring, this unit easily mounts to a standard 35mm DIN rail. As a direct replacement for the legacy 3RT1025-1AK60, it ensures a seamless transition with improved electrical endurance of up to 10 million switching cycles. Its IP20 finger-safe design and high impulse voltage resistance of 6kV make the 3RT2025-1AK60 contactor a reliable choice for technical environments requiring precision and long-term durability without the burden of constant maintenance.

• Enhanced Switching Life: Rated for up to 10,000,000 mechanical operations, ensuring longevity in high-frequency applications.
• Versatile Auxiliary Logic: Built-in 1 Normally Open and 1 Normally Closed contact eliminates the need for add-on blocks in basic interlocking setups.
• Compact Footprint: The 45mm width (Size S0) allows for high-density installation in control cabinets where space is at a premium.
• Technical Compliance: Meets global standards including UL, CSA, and CE, suitable for international machinery exports.

• Can I use this to replace an older 3RT10 series contactor? Yes, the 3RT2025-1AK60 is the functional and dimensional successor to the 3RT1025-1AK60, though you should check existing auxiliary accessories for compatibility.
• Will the coil operate on 110V systems? The coil is dual-rated for 110V AC at 50Hz and 120V AC at 60Hz, making it ideal for North American and European industrial control standard voltages.
• What is the maximum ambient operating temperature? This unit is rated to operate reliably in ambient conditions ranging from -25 to +60 degrees Celsius.
