Family Comparison — 14DUA32 Series
The eight alternates (14DUA32AA, 14DUA32AC, 14DUA32AL, 14DUA32AG, 14DUA32AF, 14DUA32AH, 14DUA32AE, 14DUA32AJ) are Siemens-issued variants sharing identical electrical and environmental specifications. The reader must verify suffix-specific traits—typically coil voltage or terminal configuration—with Siemens catalog data before substitution.
| Spec | 14DUA32AD (seed) | 14DUA32AA | 14DUA32AC | 14DUA32AL |
|---|---|---|---|---|
| Current – Output | 27A | 27A | 27A | 27A |
| Overload Range | 0.25–1 A | 0.25–1 A | 0.25–1 A | 0.25–1 A |
| Motor Type | AC Motor | AC Motor | AC Motor | AC Motor |
| Mounting | Chassis | Chassis | Chassis | Chassis |
| Operating Temp | 20°C–40°C | 20°C–40°C | 20°C–40°C | 20°C–40°C |
| Similarity | 1.0 | 1.0 | 1.0 | 1.0 |
Why similar (14DUA32AA as example): Same Siemens Class 14 Size 1 platform, same 27A output rating, same 0.25–1A overload band, same open-box chassis-mount form factor. Suffix difference alone governs coil or connection variant selection.
