Multi-pole Lightning Current and Surge Arresters for Photovoltaic Systems - Class I (B+C) and Class II (C)

The PV ISPRO BS(R) and PV ISPRO C(R) series of over voltage surge protective devices has been developed to protect against indirect lightning discharges and is intended to protect photovoltaic system.

1. PV ISPRO BS(R) is circuit topology consists of two varistor stages each protected by a thermal disconnection device.
    
2. PV ISPRO C(R) is circuit topology consists of two(three) varistor stages each protected by a thermal disconnection device.

FEATURES:

• Class I / (B+C) and Class II / (C)

• Surge discharge ratings Imax: 40 kA per pole for PV ISPRO BS(R) and 40 kA for PV ISPRO C(R)

• Housing: compact and modular
