Why Choose the ABB OVR PV T2 40-1000 P Surge Protective Device?
The ABB OVR PV T2 40-1000 P is a pluggable Type 2 photovoltaic surge protective device (SPD) designed to protect the DC side of solar photovoltaic installations against transient overvoltages caused by indirect lightning effects and electrical switching events. Part of the ABB OVR PV surge protection range, it is specifically engineered for photovoltaic applications with DC operating voltages up to 1000 V.
The OVR PV T2 40-1000 P uses a 1+1 DC configuration protecting the positive and negative PV conductors. It provides a maximum discharge current (Imax) of 40 kA and a nominal discharge current (In) of 20 kA using the standard 8/20 µs surge-current waveform, with a voltage protection level (Up) of 4 kV.
With a 1000 V DC maximum continuous operating voltage and pluggable cartridges, this ABB SPD is well suited to photovoltaic combiner boxes, inverter protection and DC distribution equipment. Visual status indication supports straightforward inspection, while the replaceable cartridge design simplifies maintenance without requiring replacement of the complete device base.
