Victron Energy Anti-Islanding Box 63A Single and Three Phase

Victron Energy Anti-Islanding Box 63A

The Victron Energy Anti-Islanding Box 63A provides a pre-wired, fully integrated solution to meet strict grid-feeding regulations for Energy Storage Systems (ESS). Designed to seamlessly interface with grid-tied inverter/charger installations, this device ensures your system automatically disconnects from the grid in the event of a power outage, protecting utility workers and maintaining network stability.

Fully Integrated Grid Protection

Housed within the unit is a combination of high-quality protective components. The core of the system is the highly regarded Ziehl UFR1001E anti-islanding relay, which constantly monitors grid voltage and frequency. This relay is paired with two in-line contactors and a main circuit breaker, providing a reliable, all-in-one hardware disconnect solution that is suitable for both single-phase and three-phase configurations.

Key Features

• Universal Compatibility: Suitable for both single-phase and three-phase electrical systems.
• High Current Rating: Rated for up to 63A per phase to support high-capacity solar and energy storage systems.
• Pre-Wired Convenience: Combines the Ziehl UFR1001E, dual contactors, and a main breaker into a single, ready-to-mount enclosure.
• Robust Housing: Enclosed in an IP65-rated casing, providing excellent protection against dust and low-pressure water ingress.
• ESS Integration: Well suited for grid-feeding inverter/charger setups requiring certified external hardware anti-islanding protection.

System Compliance and Installation

When implementing grid-tied or ESS applications, adherence to local grid codes is critical. While some inverters feature built-in software anti-islanding, specific Distribution Network Service Providers (DNSPs) mandate an external, hardware-based disconnect mechanism for larger systems. This fully enclosed unit simplifies that compliance process by providing the necessary contactors and relay in one box. Ensure you verify compatibility and specific network rules with your local authority prior to design and installation.
