On 16th January 2013 the revised standard AS/ANZ 5033:2012
installation and safety requirements for photovoltaic (PV) arrays came into
effect in accordance with Regulation 11 of the Electricity (General)
One of the new standards is that circuit breakers and switch
disconnectors used in PV arrays shall not be polarity sensitive. ABB has one of
the only two circuit breakers available on the market that currently comply
with this standard.
The ABB range of S800PV-S high performance miniature circuit
breakers complies with this standard and can be used in networks up to 1200V
S800PV-S was specifically designed for use in PV applications as it safely
extinguishes dangerous DC arcs even in case of double faults.
The main features of the S800PV-S range are:
- Safe disconnection of all poles
- Polarity independent
- Wide range of accessories
- Remote controllable with S800-RSU remote
- String protection with disconnector properties
with a rated current of
10 – 125A up to 1200V DC.
