Surge protection device SPD Ex9UEP, type II for ungrounded PV systems

Surge Protector SPD Ex9UEP, Type II, 3 Module Widths, for Ungrounded PV Systems

The surge protector SPD Ex9UEP is an advanced Type II surge protection device optimized to handle voltage surges up to 1200 V DC. Specifically designed for ungrounded PV systems, this protector provides effective protection against severe voltage surges, lightning strikes, and other electrical disturbances that may occur in photovoltaic installations. With its compact design consisting of 3 module widths, it easily integrates into the configuration of a PV system.

The SPD surge protectors Ex9UEP DC are ideal for photovoltaic applications, meeting the EN 50539-11 standards for PV Class T2 (Class II, Type 2, C). The front panel is equipped with a status display window for monitoring the device status, and a remote signal connection allows for remote control. The module plug construction enables easy module replacement without the need to switch off the device.
