The Anti-Islanding Box is a fully pre-wired and easy to install device that ensures your battery system can continue to operate in the event of a power failure.
If theoretically energy from a battery system could be fed back into the public grid in the event of a grid failure, an anti-islanding device that complies with local regulations must be installed in the battery system. If there is a power failure in the power plant, this so-called ENS disconnects from the grid and your system continues to work as an independent system.
The anti-islanding box 63A single and three-phase is a combination of an anti-islanding device, the ZIEHL UFR1001E anti-islanding relay, two inline switching devices and a main circuit breaker. It is suitable for both single-phase and three-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 integrated into a grid-fed inverter/charger (ESS) system to comply with local anti-islanding regulations.
The Anti-Islanding Box 63A for single-phase and three-phase systems meets the following standards:
- G83/2 and G59/3 (UK Proof of Conformity)
- VDE-AR-N 4105 (proof of conformity NA Schutz Germany)
- ÖVE / ÖNORM E 8001-4-712 (Certificate of Clearance Austria)
- DIN V VDE V 0126-1-1 / A1 / NOI-RES_13E (European clearance certificate)
- NRS-097-2-1 (South African Certificate of Conformity)
The German, Austrian and French standards require two electrical switching devices connected in series.
The Ziehl relay controls both switching devices.
Note: The second contactor is not needed for G83/2 and G59/3 compliant systems.
