New dc Fuses Deliver Superior Protection For ac/dc Applications

St. Louis - The new series of Cooper Bussmann midget fuses is designed to meet a full range of ac or dc applications, from dc control circuits and traction/mass transit auxiliary circuits to alternative energy sources.

The Cooper Bussmann Limitron DCM fuse is UL Listed up to 600Vac/dc and with interrupting ratings of 100,000A for ac applications and 50,000A for dc.

Developers of solar photovoltaic systems, which are used to convert solar energy into electricity for power generation, can utilize the new Cooper Bussmann DCM fuse to easily comply with NEC 690.9(D) which requires that photovoltaic source circuits utilize overcurrent devices listed for dc circuits and having the appropriate voltage and interrupting ratings. Cooper Bussmann offers a whole product solution for photovoltaic applications, including the fuse, fuse holder, combiner box (sourced), disconnect and monitoring capability.

The DCM fuse also possesses additional advantages for other alternative applications, including a 600Vdc rating for electric and hybrid-electric vehicles, and dc listing requirements for wind power, fuel cells and dc control circuits. Furthermore, its small size, listing for dc use and a variety of fuse holders makes it ideal for traction and mass transit auxiliary circuits.
