Three-phase autotransformer 16 kVA power rating Selectable primary voltages 400V secondary output UL/CSA recognized IP00 rated

Product description

The Siemens 4AP2752-8HA20-2XA0 is a three-phase autotransformer with a nominal power rating of 16 kVA. It features selectable primary voltages including 480V, 460V, 440V, 415V, and 380V, with a fixed secondary voltage of 400V. The secondary current is rated at 23.1A, and it operates at frequencies of 50-60 Hz. This autotransformer has a temperature rise of 50°C, insulation class H, and an IP00 protection rating.

This autotransformer is designed for applications requiring voltage conversion without electrical isolation, such as motor speed control, power factor correction, or voltage stabilization in industrial settings. Its UL/CSA recognition and adherence to EN 61558-2-13 standards ensure safe and effective operation. It utilizes screw connections for both primary and secondary wiring.
