Siemens Industrial Controls 3RT2026-1BB40 Contactor
The Siemens Sirius 3RT2026-1BB40 Contactor is a heavy-duty S0 size power contactor engineered for demanding motor control and industrial HVACR automation. Operating on a 24VDC control coil, this 3-pole device maintains a 25A AC-3 rating at 400V, providing a power delivery capacity of up to 11kW. Built for high-cycle reliability in panel-mount or 35mm DIN rail configurations, the 3RT2026-1BB40 features two integrated auxiliary contacts (1 NO + 1 NC) and screw terminal connections to ensure secure, vibration-resistant wiring. As a dimensional and functional successor to the legacy 3RT1026 series, this contactor integrates seamlessly into SIRIUS modular systems, allowing for easy expansion with side-mounted or front-mounted auxiliary switch blocks and surge suppressors. The IP20 finger-safe design and 6kV impulse voltage resistance make it a standard choice for magnetic motor starters and high-performance climate control circuits.
Key Benefits- Optimized Efficiency: Low power consumption 24V DC coil (approx. 5.9W) reduces heat load within the control cabinet.
- Enhanced Compatibility: Direct replacement for obsolete 3RT1026-1BB40 models, maintaining the same S0 physical footprint for quick retrofits.
- Operational Longevity: Rated for up to 10 million mechanical switching cycles, ensuring minimal downtime in high-frequency applications.
- Safe Design: Technical compliance with finger-safe standards and high shock resistance (10g / 5ms) for stable performance in rugged environments.
- Can I add more auxiliary contacts to this frame? Yes, the Siemens 3RT2026-1BB40 supports additional 3RH29 auxiliary switch blocks on both the front and sides of the unit.
- What is the maximum horsepower rating for this contactor? For 3-phase applications, it is rated at 7.5 HP at 230V and 15 HP at 460V.
- Is a surge suppressor included? No, but the unit is compatible with clip-on 3RT29 varistors or diode combinations to protect sensitive DC control circuits.
