WITHOUT LPS
If the building does not have an air termination system, there is no risk of a direct lightning strike to the building or PV system (impulse current with parameters of 10/350 µs). In this case we can install SPD type T2. HSA
PV 600 M can be a suitable SPD representative at position A, or at positions A and D when the
distance between the inverter and the panels is greater than 10 m. This product is determined specifically
for UCPV = 600 V DC, but we also offer variants for 1 000 V DC and 1500 V DC. It is in Y connection, which
is resistant to the earth fault of live conductors and has zero residual (leakage) current. If you insist
on a cheaper option, we also offer variants in the full voltage range in U connection with a marking /2
at the end of the product name. The entire product range brings the advantage of an exchangeable module
design - the products are marked with the letter M and meet the discharge capability for all LPL levels.
It is equipped with an internal DC arc fault disconnector and therefore no back-up fuse is required. If
remote monitoring of the surge protection status is required, the variants marked S can be used, i.e.
for example HSA PV 600 M S. The potential-free contact of this remote monitoring is then
connected to the building‘s control system (typically as an input of a PLC control system), where it permanently
informs the investor about the status of the surge protection device, without the need for physical control
of the switchboard.
Unless otherwise specified in the risk assessment, a suitable representative of the SPD in position C
can be a SPD type T2, for example HSA-275/3+0 M S, assuming an electrical distribution
of 3 x 230 V / 50 Hz, in a TN-C configuration. The marking M specifies the design with exchangeable module,
S specifies the design with remote monitoring. If the entire electrical distribution of the building is
TN-S, the HSA-275/4+0 M S configuration can be used. If we consider a three-phase TN-S
system, a suitable representative is, for example, HSA-275/3+1 M S. The entire range of SPDs for the AC side is also available in an unchangeable design.
