enwitec overvoltage protection DC type II, 1 MPPT, terminals

DC overvoltage protection, type II for 1 MPP

Compact and pre-fabricated box with type II surge arrester for the DC side. Suitable for INV with only 1 MPP up to 1100 V DC voltage. This overvoltage box has 2 input terminals each with spring-type terminal contacts per pole and arrester. Here, cable end sleeves are not required. This results in an even larger contact area and low contact resistance. The output terminal is also screwless.
