enwitec overvoltage protection Mersen DC type II, 2 MPPT, terminals

DC overvoltage protection, type II for 2 MPP (Mersen)

Range of application: Buildings without external lightning protection, in compliance with VDE 0100-443 and 0100-534

Compact and pre-assembled box with type II surge arresters for the DC side. Suitable for inverters with 2 MPPT up to 1000 V DC voltage. This surge box has 2 input terminals per MPPT with spring loaded terminals per pole and arrester. No wire end ferrules are needed here. This means that the contact area is even larger and the contact resistance is low. The outgoing terminal is screwless as well.
