AC 10KW 25A Type B Three-Phase + Backup Protection - Technideal

AC 10kW Three-Phase Backup Box with Backup – Type B

Automatic changeover box for grid outages and three-phase AC electrical protection for hybrid inverters without galvanic isolation (Sofar-HYD, Fronius).

Mandatory for any grid-connected installation with a grid-tied hybrid inverter

This box has 2 AC outputs: 

• A grid AC output that powers the part connected to the electrical grid (self-consumption)
• A backup output that powers the part isolated from the electrical grid in case of a power outage

Automatic changeover and complete backup mode for photovoltaic installations equipped with hybrid inverters without galvanic isolation.

In the event of a power failure, the transfer switch safely disconnects the photovoltaic system from the electrical grid and simultaneously provides backup power to your home. Thanks to the ready-to-connect and pre-tested solution, you no longer need to self-assemble the switching device.

Box composition:

• 1 x ID Inter Diff 25A 30mA Type B 4 Pole
• 1 x ID Inter Diff 25A 30mA Type Ai 4 Pole
• 1x Contactor KM1 NO
• 1 x Circuit Breaker DPN 2A 2 Pole Curve C
• 2 x Circuit Breakers DPN 32A 4 Pole Curve C
