The SITAS 4AM3242-5FT10-0FA0 is the 500V-primary variant in the 63VA SITAS range, converting a 500V three-phase feeder to a safety-isolated 230V single-phase control supply. In mining operations, steel mills, and heavy industrial plants where 500V distribution is standard, this transformer eliminates the need for a separate 500/400V step-down transformer before the control transformer — it connects directly to the 500V bus.

500V Grid Compatibility

The ±5% primary tapping (475/500/525V) accommodates the voltage variation typical of 500V industrial networks, particularly in older European facilities where the nominal voltage has drifted over decades of infrastructure upgrades. The secondary delivers 230V at 0.27A continuous, with 190VA short-time capacity for energizing multiple contactors. The EI 84/28 core and 8.4% short-circuit voltage define the transformer's impedance and inrush characteristics — standard values for the 63VA SITAS class.

Industrial-Grade Construction

The laminated iron core and vacuum-impregnated windings provide mechanical robustness and moisture resistance suitable for the vibration and temperature cycling of heavy industrial environments. The 86×98×90mm footprint fits standard panel layouts. CE, UL/CSA, and cRUus certifications support global deployment. As with all SITAS transformers, IP00 rating requires installation inside a closed electrical cabinet. Thermal class B allows 40°C ambient maximum at full rated load.

Key Decision Parameters
