Photovoltaic fuses

概述 Overview

MDPV-30 系列光伏熔断器主要用于太阳能光伏发电直流汇流箱中，对可能产生的太阳能的
电池板光伏组件及逆变器的电流反馈所产生的线路过载和短路电流进行分断，从而起到保护
太阳能光伏组件板之用，熔断器也可选配在其它任何直流电路中作为对电器元件的线路过载
和短路保护之用。
The MDPV-30 series of photovoltaic fuses are mainly used in the solar photovoltaic power
generation DC combiner box to break the line overload and short-circuit current generated
by the current feedback of the solar panel photovoltaic modules and inverters that may
generate solar energy, thereby protecting For the use of solar photovoltaic panels, fuses
can also be optionally used in any other DC circuit for line overload and short circuit
protection of electrical components.
