Find clear answers about ArcShield specifications, installation procedures, and compliance standards.
ArcShield is an all in one DC protection enclosure that combines DC isolation, string protection fuses, and aerosol fire suppression into a single pre-wired enclosure engineered for commercial PV arrays.
Yes. ArcShield is IP65 weatherproof and IK10 impact rated, with operating temperature tolerances ranging from -35°C to +65°C, making it fully rated for harsh rooftop environments.
Yes, ArcShield can be configured from 1 up to 10 isolator channels with custom cable entries or MC4 connectors based on your project specifications.
The aerosol unit is completely self contained and operates independently of the PV electrical circuit, activating only if thermal thresholds inside the enclosure are exceeded.
ArcShield is designed for solar systems with a maximum system voltage of 1000V DC. The pre wired DC isolators are rated at 32A.
ArcShield uses 20A gPV fuses in 10 × 38mm format, providing dedicated fuse protection for each PV string. The fuse protection is designed to help protect against reverse current and unintended parallel current paths.
Yes. ArcShield is supplied with pre wired DC isolators, MC4 panel connectors and 6mm² PV1-F cable, helping installers achieve a cleaner and more efficient installation.
The ArcShield enclosure is rated IP65 / IK10 and features an ABS body with a polycarbonate clear door. It is also key-lockable and supplied with external fixing brackets.
Yes. ArcShield incorporates a self contained LFE10G aerosol suppression device. The device operates independently of the PV electrical circuit and provides an additional protective layer inside the enclosure.
ArcShield can currently be configured from 1 to 10 isolators, with project pricing available for configurations requiring 11 or more isolators.
Yes. ArcShield is designed with demanding commercial and professional PV installations in mind, providing integrated protection in a purpose built enclosure.
The enclosure is specified for an operating temperature range of -35°C to +65°C.
Yes. For projects requiring 11+ isolators, customers can contact the ArcShield team for project-specific pricing.
Yes. ArcShield includes Stäubli MC4 connections rated for 1000V DC, with an IP67 rating when properly mated.
ArcShield is available directly through the online store. You can select the required number of isolators and configure your ArcShield solution before purchasing.
