Siemens 14JUH32AA Heavy Duty Motor Starter, NEMA Size 4, Solid State Overload

Description

The Siemens 14JUH32AA is a heavy duty motor starter engineered for demanding three-phase motor control applications in commercial and industrial HVAC and mechanical systems. Built to NEMA Size 4 standards with a Frame Size B configuration, this starter delivers robust, reliable performance across a wide range of motor loads.

Key Features

• Dual coil voltage compatibility: 110–120V AC and 220–240V AC for flexible installation
• Three-phase, 3-pole design for full motor protection and control
• 50–200 amp overload rating to accommodate a broad range of motor sizes
• NEMA Size 4 rating for high-horsepower motor starting applications
• Frame Size B construction for standardized panel and enclosure integration
• Open type enclosure for use in protected or panel-mounted environments
• Solid state overload relay for precise, electronic motor protection
• Auto/Manual reset capability for operational flexibility and safety

Solid State Overload Protection

The integrated solid state overload relay provides accurate, electronic overload protection that eliminates the mechanical wear associated with traditional bimetallic overloads. The auto/manual reset option allows technicians to configure the starter for automatic recovery in unattended applications or manual reset where operator intervention is required before restart.

NEMA Size 4 Performance

Designed for heavy duty motor starting duty, the NEMA Size 4 rating ensures this starter can handle the high inrush currents and continuous load demands of large commercial HVAC compressors, pumps, fans, and other three-phase motor-driven equipment. The open type enclosure is ideal for installation within a larger control panel or enclosure assembly.
