Inverter Connection Switchgear with AC Surge Arrester Type 2, C20A 3-F

The three-phase AC PV combiner box plays a key role in the safe operation of commercial and residential solar installations. Equipped with a type 2 surge arrester and a C-characteristic miniature circuit breaker, it directly protects the inverter against the effects of grid overvoltages. The external housing shows full resistance to UV radiation, facilitating outdoor installation. Properly selected components provide necessary photovoltaic protections, reducing the risk of downtime and costly equipment failures.

Key features

• A maximum discharge current (Imax) of 40 kA guarantees high effectiveness in suppressing harmful overvoltages.
• The IP65 protection class and a wide operating temperature range from -25 to +60 ºC enable safe outdoor installation.
• The rated insulation voltage Ui of 400 V AC and 1500 V DC ensures the electrical stability of the circuits.
• A workspace accommodating 12 modules facilitates easy wire routing and convenient service access.
• The three-pole circuit breaker with a 20 A rated current responds quickly and precisely to grid overloads.
