Siemens Industrial Controls 3RT2038-1AC20 Circuit breaker
The Siemens 3RT2038-1AC20 is a heavy-duty SIRIUS S2 power contactor designed for demanding commercial and industrial HVACR applications. Engineered for switching motors and inductive loads in the AC-3e/AC-3 category, this 3-pole unit provides a robust 65A rated current (80A in specific AC-3 applications) and is suitable for power ratings up to 37 kW at 400V. The integrated 24V AC 50/60 Hz coil ensures compatibility with standard low-voltage control circuits typical in modern automation and climate control systems. Built with high contact reliability, this model features screw terminals for secure, vibration-resistant wiring and includes one 1NO and 1NC auxiliary contact for immediate feedback or interlocking functionality. Its compact, space-saving frame allows for high packing density within control cabinets, making it an ideal choice for contractors managing complex load distribution for IE3 and IE4 efficiency-class motors. This Siemens Sirius 3-pole contactor is climate-resistant and approved for global use, ensuring dependable motor control even under harsh operational conditions.
Key Benefits- High Power Capacity: Rated for up to 80A (AC-3) and 37 kW, making it suitable for large motor starting and heavy inductive loads.
- Integrated Auxiliary Contacts: Built-in 1NO and 1NC contacts facilitate immediate signaling and control circuit integration without extra modules.
- Compact S2 Frame Size: Maximizes cabinet space without sacrificing switching performance or thermal dissipation.
- Reliable Screw Connections: Durable screw terminals ensure a maintenance-friendly and safe electrical connection.
- Global Standards Compliance: Fully certified for IEC, UL, and CSA applications, featuring finger-safe protection for technician safety.
Is the 3RT2038-1AC20 compatible with 24V DC control systems?
No, this specific model features an AC-operated coil designed for 24V AC at 50/60 Hz. For DC control circuits, a different part number from the SIRIUS 3RT2 range is required.
Can I expand the number of auxiliary contacts on this contactor?
Yes, the S2 size basic unit allows for the addition of front-mounted or laterally-mounted auxiliary switch blocks to increase the NO/NC contact count as needed.
Is this contactor suitable for IE3 or IE4 efficiency motors?
Absolutely. The 3RT2 series is specifically designed and tested for the higher inrush currents associated with premium-efficiency motors common in modern HVACR installations.
