The Victron Energy Anti-Islanding Box 63A is a pre-wired grid-protection assembly for single-phase and three-phase ESS installations. It combines a Ziehl UFR1001E anti-islanding relay, two in-line contactors and a main circuit breaker, with a rating of up to 63A per phase. The complete assembly is housed in an IP65 enclosure for protected installation.
Designed for grid-feeding inverter/charger systems, the box helps installations meet applicable local anti-islanding requirements by disconnecting generation when grid conditions fall outside permitted limits. Its integrated, pre-wired design simplifies installation and reduces the need to assemble separate protection components.
