AC Combiner Box Three-Phase 16 A with Type 2 SPD and 100 mA Type A RCD
The alternating current combiner box is the protection board to be installed on the AC side of the photovoltaic system, between the three-phase inverter output and the building's main board. This version is rated for a nominal current of 16 A per phase and brings together in a single watertight wall-mounted box all the protections required for parallel connection to the distribution grid.
The box contains a Type 2 surge protective device (SPD) that limits the overvoltages induced by indirect lightning strikes and by grid switching operations, protecting the inverter electronics, a 16 A three-phase miniature circuit breaker for overload and short-circuit protection and for isolation, and a 100 mA Type A residual current device, suitable for detecting the pulsating unidirectional fault currents typical of static converters as well.
Key features
Surge protectionThe Type 2 surge arrester diverts to earth the pulses induced by indirect lightning strikes and by grid switching operations, protecting the inverter.
100 mA Type A RCDType A trips on alternating and pulsating unidirectional leakage currents, as required for circuits supplied by inverters.
16 A three-phase MCBProtects the AC line against overloads and short circuits and allows the system to be isolated manually and safely.
Intermediate ratingThe 16 A per phase setting covers medium-power three-phase photovoltaic systems, between the 10 A and 20 A versions of the same range.
IP65 - IK08 watertight enclosureThe box, made of halogen-free recyclable plastic, is dust-tight and protected against water jets, resistant to UV rays and impacts.
Ready to installSupplied already wired and tested: it reduces installation times and the risk of errors compared with on-site assembly.
