FAQs
The RGHDCW3300WM is a high-capacity PV Guard MCCB designed for up to 1000 V DC and 3000 A. It requires standard MCCB mounting provisions and compatible bus connections within a protective enclosure. Ensure proper derating for ambient temperature and secure cable terminations using manufacturer-recommended torque specs. The unit’s size and weight necessitate appropriate support within a dedicated electrical cabinet.
Key specs are the amperage rating (3000 A) and voltage rating (1000 V DC), along with certifications (UL Listed, IEC Rated, CSA Certified). These determine fault interruption capabilities, system compatibility, and regulatory compliance. For PV plants, confirm inverter and string protection alignment, ensure adequate clearances, and verify compatibility with PVGuard-related protection schemes.
Yes. The RGHDCW3300WM is engineered for large DC protection tasks, offering a 3000 A interrupting capacity and 1000 V DC rating. Its PVGuard orientation supports PV system protection, and its certifications meet utility procurement requirements. When deploying at scale, coordinate with Eaton components for cohesive protection coordination and simplified spares management.
The unit is UL Listed, IEC Rated, and CSA Certified. These certifications validate safety, performance, and reliability across multiple jurisdictions, ease regulatory approvals, and provide assurance to utilities and end users. For projects with cross-border installation or multi-site compliance, these marks help standardize protection practices and reduce certification overhead.
The RGHDCW3300WM’s robust construction and standardized Eaton PVGuard integration support longer service intervals and easier fault diagnostics. By consolidating protection into a single high-capacity device, maintenance costs decline, spare parts converge with existing inventory, and project timelines shorten, delivering a favorable total cost of ownership for solar installations.
