FAQs
Follow Eaton’s installation instructions for DC distribution in PVGuard configurations. Ensure proper DC bus isolation during commissioning, use correct torque on terminals for 1600 A conductors, and verify wiring meets 1000 VDC ratings. The unit’s 102 lb enclosure should be securely mounted in a rated cabinet or switchgear enclosure to maintain safety clearances and drainage from outdoor exposure.
Yes. The device is explicitly rated for 1000 V DC and 1600 A, making it suitable for utility-scale PV protections and heavy DC bus protection. Its DC integration supports reliable fast-trip behavior, reducing fault propagation and enabling safe energization, with compatible auxiliary signaling options for remote monitoring.
The RGHDCW3160WMA12 carries UL Listed, IEC Rated, and CSA Certified certifications. These approvals validate safety, performance, and cross-border compatibility, simplifying procurement for multinational projects and ensuring adherence to regional electrical codes, safety standards, and utility requirements during design, installation, and maintenance phases.
Yes. The 2A/2B auxiliary contact provides signaling outputs compatible with many PV monitoring and SCADA systems. This enables remote trip indication, fault signaling, and integration with building management or energy management systems, improving situational awareness and reducing response times during faults or maintenance events.
PV Guard breakers reduce downtime by delivering reliable, fast fault interruption and clear signaling to control systems. The rugged enclosure and long service life minimize replacements and field service, while certified protections reduce compliance costs. For projects with frequent climate stress or remote locations, the total cost of ownership improves through lower maintenance frequency and higher system availability.
