Siemens Industrial Controls 14DUC32AA Starter

The Siemens 14DUC32AA Starter is a NEMA Size 1 heavy duty motor starter engineered for reliable across-the-line starting of three-phase motors. This Class 14 non-reversing starter features a dual-rated 110-120/220-240Vac coil, providing versatility for various control circuit voltages common in industrial HVACR and pumping applications. This 3-pole motor control unit is built on a Frame Size A1 and utilizes an open type enclosure intended for installation within a larger control panel.

For motor protection, the unit is equipped with a high-performance ESP200 solid state overload relay. This relay offers a 3-12 Amp overload rating and includes trip class settings (Class 5, 10, 20, or 30) to match specific load profiles. The electronics are designed to detect phase loss in under three seconds, ensuring rapid protection against single-phasing. With a 3-phase motor starter rating of 5 HP at 460V, the Siemens 14DUC32AA provides mechanical durability for millions of cycles. The solid state overload with auto/manual reset maximizes uptime by allowing field technicians to configure the reset logic to suit site-specific requirements.

• Precision Protection: The ESP200 solid state overload provides accurate current sensing and phase loss protection.
• Voltage Versatility: Dual-rated 110-240V AC coil minimizes the need for multiple stocking units and simplifies field replacements.
• Industrial Duty: NEMA Size 1 construction ensures the ruggedness required for demanding commercial HVACR compressors and blowers.
• Flexible Reset: Features a selectable auto/manual reset to streamline troubleshooting and system recovery.
