The demand for alternative energy has led to another innovation from Cooper Bussmann, the industry leader in circuit protection. Developing sophisticated solar panel systems have accelerated the demand for high performance fuses. The short-circuit conditions associated with solar panels do not allow for sufficient current to open a standard fuse in a way that effectively isolates faulted photovoltaic (PV) strings. The new Cooper Bussmann® PV Fuse line provides a full range of protection that traditional fuses cannot. Low Level Fault Protection.
PV Fuses are tested to withstand cycling conditions associated with solar panel system operation and environmental influences.
PV Fuses are designed with a maximum operating voltage based on typical solar panel systems with L/R of 1ms and below. Globally Accepted 10x38mm Dimension.
All PV Fuse amp ratings are available with standard ferrule, bolt and versatile PCB mount options.
Mersen’s HP10M photovoltaic (PV) fuse series was developed specifically for the protection of PV string wiring for 1000VDC industrial rooftop and utility scale photovoltaic systems. Its robust construction makes it ideal for continuous temperature and current cycling withstand adding to system longevity. The 1000VDC rated HP10M, designed for low minimum breaking capacity capabilities of 1.35 times the fuse rated current value, allows for safe circuit interruption under typical low fault current conditions produced by PV arrays. In addition to the standard ferrule terminal, parts are available with Crimp Cap terminals for in-line fuse applications. The unique wire crimp terminal (CC option) permits solderless wire-to-fuse connection for overmold encapsulation of fuse and wiring. Protect your off-grid or grid tied PV system from unexpected string faults using Mersen’s HelioProtection® fuse line.
Low fault current interrupting capability
Durable construction for enhanced system longevity
Mersen UltraSafe Modular Fuse holders introduce a new level of safety for Class CC (USCC) and Midget 1-1/2" x 13/32" (USM) AC and DC rated fuses up to 30 amperes. UltraSafe holders qualify as “Fingersafe” under IEC and DIN standards to an IP20 grade of protection, including fuse changing (with the flick of a finger). UltraSafe holders are available in 1, 2, 3 or 4 poles, with or without visual blown-fuse indicators in each pole. Multi-pole units can also be field assembled by ordering pin-tie handles. UltraSafe holders save up to 15% mounting space and any combination can be snapped onto 35mm DIN-rail for extra savings in panel building time. UltraSafe holders with Class CC fuses chosen for Type “2” No Damage protection give one of the safest protection packages in the industry. UltraSafe body material is tough and durable polyamide, with exceptional insulating properties.
