The RP ONESTO changeover switch handles 40A across four poles and operates at 400V/50Hz. The 1-0-2 position layout lets you select source 1, off, or source 2 directly from the panel, making it suitable for transfer between mains and a backup generator on a four-pole circuit.

The unit clips onto a standard DIN rail and complies with IEC/EN 60947-3, the international standard for switches and disconnectors used in low-voltage distribution.
