Phoenix Contact

6 products

The Phoenix Contact products in the catalogue: surge protective devices for the DC side of solar installations, with the VAL-SPP-T2-1000DC-PV-2+V-UT in type 2 up to 1000V, the VAL-SPP-T1-1000DC-PV-2+V-UT-R in type 1+2 with remote signalling contact and the VAL-MS-T1/T2 600DC-PV/2+V for voltages up to 720V.

The 2+V designation describes the internal circuit: two varistors between the poles and earth plus a spark gap in series, an arrangement that avoids the permanent leakage currents to earth of varistor-only devices.

The remote contact matters on monitored systems: it tells the data logger a cartridge is spent, instead of waiting for a visual inspection.
