DC+AC Combiner Box with Type 2 SPD, 2 Strings 2 MPPT, 32A Three-Phase and 100mA RCCB

Combined DC+AC combiner box for photovoltaic systems with three-phase inverters, also complete with residual current protection. It collects 2 PV strings on 2 MPPT inputs and brings together in a single enclosure all the protective devices required upstream and downstream of the inverter.

The DC side is protected by a Type 2 surge protective device for 1000V DC; the AC side by a Type 2 SPD, a 32A three-phase miniature circuit breaker and a 100mA Type A residual current circuit breaker, sensitive to alternating and pulsating unidirectional fault currents. The 100mA threshold is chosen to limit nuisance tripping caused by the earth leakage currents typical of photovoltaic generators, while still ensuring protection against indirect contact.

Key features

Integrated 100mA Type A RCCBEarth fault protection already on board the box: Type A responds to alternating and pulsating unidirectional leakage currents.
100mA threshold against nuisance trippingThe 100mA setting reduces unwanted disconnections caused by the capacitive leakage currents typical of a PV array.
32A three-phase MCBIt protects the AC line against overload and short circuit and allows it to be isolated safely.
2 strings, 2 MPPTThe two strings remain independent up to the inverter, keeping maximum power point tracking separate.
Type 2 SPD on DC and on ACSurge arresters on both sides of the inverter against induced and switching overvoltages.
Complete, pre-wired boxAll the DC and AC protective devices in a single compact wall enclosure, already assembled and ready for connection.
