The Anti-Islanding Box 63A single and three phase is a combination of an anti-islanding device, the Ziehl UFR1001E, two in-line contactors and main circuit breaker. It is suitable for both single phase or 3 phase systems. It is rated up to 63A per phase and all parts are conveniently housed in an IP65 rated enclosure.

The Anti-Islanding Box can be added to a grid-feeding inverter/charger system (ESS) to meet local anti-islanding regulations.
