AC Combiner Box 16A Three-Phase with Type 2 SPD and 300mA Type A RCD
Alternating current combiner box for three-phase photovoltaic systems, complete with residual current protection. It is installed on the AC side between the inverter output and the distribution board and brings together in a single enclosure all the protections required on the grid connection line: overcurrent protection, residual current protection and surge protection.
The equipment includes a 16A miniature circuit breaker against overloads and short circuits, a Type 2 surge protective device (class II) against transient overvoltages caused by indirect lightning strikes and switching operations, and a 300mA Type A residual current device. The 300mA sensitivity is the value typically used for protection against fire risks due to earth leakage currents; Type A ensures tripping even with pulsating unidirectional fault currents, the kind that can occur downstream of electronic equipment such as photovoltaic inverters.
Key features
Complete protection set16A miniature circuit breaker, 300mA Type A RCD and Type 2 surge arrester in a single pre-wired box.
Type A RCDTrips on alternating and pulsating unidirectional earth fault currents, suitable where power electronics are present.
300mA sensitivityA setting aimed at protection against fire risks caused by earth leakage.
Type 2 surge arresterLimits transient overvoltages coming from the grid, protecting the inverter and the downstream loads.
16A three-phase ratingSuitable for inverters with an indicative power of up to about 11kW on a 400V grid.
Tidy installation319 × 259 × 144 mm for 2.6 kg: a single wall-mounted enclosure instead of several devices scattered across the distribution board.
