Protection
Fusible
Fusible protection provides targeted fault interruption at 30A, limiting fault current and protecting conductors. This translates into lower arc-flash exposure for technicians and reduced risk of equipment damage during PV string faults. In solar installations, this protects ungrounded DC circuits and supports safer commissioning and maintenance. NEMA 3R, painted galvanized steel enclosure offers outdoor durability against weather, corrosion, and impact. The rugged enclosure reduces downtime in exposed sites and simplifies serviceability. It is well suited to rooftop, carport, and ground-mounted PV arrays where reliable protection matters. 600 VDC system rating and a single circuit design cover typical residential and light commercial PV strings while maintaining a compact footprint. The lug connections handle #14-#2 AWG lugs and #14-1/0 AWG solid returns, streamlining installation and reducing field labor. Certifications NEC 690 per UL 1741 and UL 98B provide installer confidence in code compliance and long-term reliability. Product dimension tables help select the right ampere configuration for each project, avoiding over- or under-sizing. Series DC Photovoltaic Applications ensures compatibility with standard PV protection practices and supports consistent field wiring across multiple sites, accelerating procurement and installation timelines.
