Pv Disconnector DC ISOLATOR IP66NW WITH MC4 connector

Isolator switch (also known as a main isolator switch) are devices or systems that isolate a particular circuit for maintenance and prevent currents from passing through. These switches are used for a range of electrical appliances and applications, including power grids, solar system etc.

MDIS-40MD DC Isolator Switch with breathing valve and MC4 have been specifically designed to switch Direct Current(DC) at voltages up to 1200v.Professional design and the ability to switch such voltages at rated current mean they are ideal for switching protection in photovoltaic (PV) systems. In some countries, all PV systems are required to have PV switches. This photovoltaic switch with waterproof casing has IP66 waterproof ability, which perfectly completes the isolation task of outdoor photovoltaic system installation.

DC isolating switch is mainly used for line isolation between components and inverters in photovoltaic power generation system. The waterproof property of the product reaches IP66. The inner core of the product can be installed inside the inverter for controlling the input line of the inverter.DC isolating switch is suitable for isolation protection of lines with working voltage up to 1000V DC and rated current up to 32A, which realizes load interruption and effective isolation. It is mainly used in photovoltaic field.The DC isolating switch solves the problems that the insulation strength of the insulator decreases or the AC/DC short circuit accident occurs when the AC motor leaks electricity due to the damage of the insulator between the housing of the AC motor and DC decelerating mechanism or other reasons in the operation system of the DC isolating switch in the existing technology,which effectively guarantees the safe operation of power supply rectifier equipment, to prevent major economic losses and personal injury.
