AC Combiner Box Three-Phase 10 A with Type 2 SPD and 100 mA Type A RCD
The alternating current combiner box is installed on the AC side of the photovoltaic system, between the three-phase inverter output and the building's main board. It is the version sized for small inverters, with a rated current of 10 A per phase, and it brings together in a single watertight wall-mounted box the protections required for parallel connection to the grid.
Inside it there are a Type 2 surge protective device (SPD) that diverts to earth the surge pulses induced by indirect lightning strikes and by grid switching operations, a 10 A three-phase miniature circuit breaker with curve B for protection against overloads and short circuits, and a 100 mA Type A residual current device, able to detect the pulsating unidirectional fault currents produced by the inverter electronics as well.
Key features
Type 2 surge arresterThe Noark Type 2 surge arrester protects the inverter and the AC installation against the overvoltages induced by indirect lightning strikes and grid switching operations.
10 A curve B MCBCurve B, with fast tripping, suits lines with low inductive loads and ensures overload and short-circuit protection for the inverter.
100 mA Type A RCDDetects alternating and pulsating unidirectional leakage currents, as required for circuits supplied by static converters.
Suitable for small invertersThe 10 A per phase setting is designed for three-phase photovoltaic systems of modest power.
IP65 - IK08 watertight enclosureBox made of halogen-free recyclable plastic, resistant to UV rays and impacts, suitable for outdoor mounting.
Wired and testedThe box is supplied already assembled and tested, reducing installation times and wiring errors.
