Product Description
The SITAS 4AM3242-8DN00-0EA0 replaces three single-voltage transformer part numbers with one. Its multi-tap primary — 480V, 500V, 525V — covers the distribution voltages found in North American industrial facilities (480V), European heavy industry and mining (500V), and marine/offshore electrical systems (525V). For an OEM building machines destined for multiple regions, or a maintenance department supporting plants on different grids, one stocked part number serves all three voltage environments.
Multi-Tap Flexibility
Unlike the ±5% tap variants that fine-tune around a single nominal voltage, the 8-prefix multi-tap models provide genuinely different primary voltage options — the installer selects the appropriate terminal at commissioning based on the measured supply voltage. The secondary delivers a fixed 24V at 2.63A continuous, with the standard 190VA short-time (S6) surge capacity for contactor and relay inrush. Changing the primary tap requires no tools beyond a screwdriver to move the supply connection to the correct terminal.
Standardized Platform
All SITAS 63VA transformers share the same EI 84/28 core, 86×98×90mm footprint, 85% efficiency, 8.4% short-circuit voltage, and II0 vector group. This standardization means panel designs can accommodate any primary voltage variant without mechanical re-engineering — the mounting footprint, terminal layout, and thermal contribution to the enclosure are identical across the entire 63VA family. The transformer is safety isolating per EN 61558-2-6 and recognized under CE, UL/CSA, and cRUus.
