0SPF03.5T电路保护的保险丝规格书PDF中文资料

0SPF03.5T属于电路保护的保险丝。由力特公司制造生产的0SPF03.5T保险丝保险丝是一种用于在电流超过一定限值时阻断电流（过流保护）的器件。保险丝通过在位于两个终端之间的材料中创建开路来工作。随着电流变化，保险丝产生的热量增加，材料将会熔化（熔断）。保险丝熔断所需的时间通常定义为快速熔断或慢速熔断。

描述 Description

The SPF Solar Protection Fuse series has been specifically

designed for the protection of photovoltaic (PV) systems.

This family of midget-style fuses (10 x 38 mm) can safely

protect PV modules and conductors from reverseovercurrent conditions.

As PV systems have grown in size, so have the

corresponding voltage requirements. This increase in

system voltage has typically been intended to minimize

power loss associated with long conductor runs. Standard

circuit protection devices are not designed to completely

protect photovoltaic panels. However, the SPF series is

UL Listed to safely interrupt faulted circuits up to this

demanding voltage level.

Littelfuse offers multiple ampere ratings to match specific

requirements in a variety of applications.

Features/Benefits

 Full range, fast-acting fuse helps eliminate common lowoverload faults  Prevents power generation losses due to nuisance

tripping from changes in temperature

 Both PCB mount and dead-front holder options available

Applications

 Inverters  Combiner boxes

 Battery charge controllers
