With an enclosure of IP65, the enclosed bypass switch is the smallest footprint bypass switch for online operation which provides isolation for safe service and maintenance. It is a manual operated switch for overriding equipment in case of their failure or maintenance, hence reducing downtime. The enclosed bypass switches have three stable positions: I (Frequency inverter), 0 (OFF), and II (Bypass). The enclosure is UV protected polycarbonate, making the switch suitable for indoor and outdoor use.
