Cooper Bussmann, the leader in critical circuit protection, power management and electrical safety, is launching a new modular fuse holder for PV applications. Designed to accept its 10 x 38 range of 1-20 Amp PV fuse links, the fuse holder offers a number of benefits including space saving, speed of installation and global acceptance.
Manufactured from self-extinguishing UL 90V-0 rated polyester, and featuring an ultra-sonic welded body, the fuse holder boasts a 10 percent smaller footprint than previous versions, making it the smallest, most compact unit on the market. This is a real bonus for system OEMs as they look to save space in equipment.
In addition there are a number of features which simplify and speed up installation. DIN rail mounting is effortless and requires no tools thanks to the built-in spring loading feature. A choice of either cable or spade lug connection is available. The box lug cable terminal is supplied at its maximum aperture, negating having to loosen the terminal screw before tightening back up; and accepts 1mm2 up to 25mm2 cable or a 6mm busbar connection. The wire strip length indicator on the body provides guidance on how far to strip back the cable insulation. All connections can then be secured by the captive, backed-out, phil-slot screw.
Once installed the fuse holder has a number of key safety features including a wire security tag hole and a 4mm lockout device mounted on the fuse carrier. An optional open fuse indicator is available. Rated up to a 1000Vdc for use with solar gPV fuses, the fuse holder carries IEC, cULus, CSA, UL and CCC accreditations, allowing the selection of one fuse holder that meets global requirements.
The new fuse holder is colour-coded yellow to signify its use in solar applications and comes in single and double pole variants. With the launch of the new modular fuse holder for PV applications, Cooper Bussmann has further enhanced its range of complementary circuit protection products for equipment OEMs and system builders, providing global solutions from one source.
