Littelfuse Introduces New SPF Solar Fuse Series


Littelfuse Inc. has released its new SPF Solar fuse, which is intended to offer protection for solar photovoltaic applications in excess of 1000 V DC in a compact 10 mm X 38 mm midget package.

Due to the advances in technology and the drive for higher efficiency, today's PV circuit constraints have become more severe than can be protected with commonly used circuit protective devices and circuit breakers, the company says. The SPF series was designed to specifically address the PV industry's needs.

‘As PV systems have grown in size, so have their circuit protection requirements, such as voltage rating,’ notes Doug Mlecczko, product manager at Littelfuse. ‘The SPF family protects PV modules and conductors from the potentially devastating effects of a low short-circuit current in systems upwards of 1000 V DC.’

The UL-recognized SPF series offers 13 different ampere ratings, from 1 ampere up to 30 amperes, to match ever-changing designers' requirements for many PV applications, the company adds. Such applications include combiner boxes, inverters and battery charge controllers. Each fuse is lead-free and RoHS-compliant, offering additional environmental friendliness.
