AC Combiner Box 20A Single-Phase with Type 2 SPD
Alternating current combiner box for single-phase photovoltaic systems: it is installed on the AC side of the system, between the inverter output and the building's electrical distribution board. It is the pre-wired solution for creating a tidy, quick protection point on the line connecting the inverter to the grid, avoiding the need to assemble a dedicated enclosure on site.
Inside are a 20A miniature circuit breaker, which protects the AC line against overload and short circuit and allows the inverter to be isolated for maintenance work, and a Type 2 surge protective device (class II), which limits surges of indirect atmospheric and switching origin coming from the grid, protecting the inverter electronics. A current of 20A on a 230V single-phase grid corresponds roughly to inverters up to about 4.6kW.
Key features
AC line protectionThe 20A miniature circuit breaker protects the cable between the inverter and the main board against overloads and short circuits.
Type 2 surge arresterThe class II SPD limits surges induced by indirect lightning strikes and grid switching operations, safeguarding the inverter.
Pre-wired and ready to useThe box is already assembled: only the line coming from the inverter and the one going to the distribution board need to be connected.
Sized for single-phase systems20A on a 230V grid: a size suited to single-phase inverters with an indicative power output of up to about 4.6kW.
Compact footprintEnclosure measuring 202 × 201 × 120 mm and weighing 1.1 kg, which can be wall-mounted next to the inverter.
Inverter isolationThe circuit breaker makes it possible to isolate the inverter from the grid during maintenance and inspections.
