0SPF025.T电路保护的电气专用保险丝规格书PDF中文资料

0SPF025.T属于电路保护的电气专用保险丝。由力特公司制造生产的0SPF025.T电气专用保险丝该系列产品用于过电流故障保护，其作用是防止电流超过所需最大值而导致设备内的导电元件损坏。这些保险丝与普通保险丝的区别在于以下几个因素之一：具有 UL248 标准下的非辅助性分类、在危险或爆炸性环境中使用的认证，或辅助性设备保护产品中不常见的外形尺寸，如具有指示功能或可熔电缆链路的保险丝和指定用于特定应用（例如电信电路或万用表的保护）的保险丝。

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
