MDIS-40 32a 4 Pole 1000V 1200V Solar Dc Isolator Switch

Isolator switches (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, kitchen tools, and so much more.

The MDIS series of MDIS-40 is used to switch direct current (DC) systems at voltages up to 1200v. Their clever design means they are ideal for switching in photovoltaic (PV) systems. Due to advanced manufacturing capabilities, disconnectors have high stability. The housing material PC enables the isolating switch to work at full load in the range of -5℃~+40℃.
