Phoenix Contact 1197145 Generator Connection Box (GAK) for Photovoltaic Systems, 2-String, 1000 V DC, IP65

Photovoltaic installations need a safe, code-compliant point to combine and disconnect DC strings before the inverter. The Phoenix Contact 1197145 Generator Connection Box (GAK) solves this by integrating string fuses, surge protection, and a DC load-break switch in one IP65 enclosure.

Who is it for

Solar installers and system integrators working on residential or commercial PV arrays up to 1000 V DC. It suits two-string configurations where each string carries up to 15 A, with a total input current of 30 A.

Main features

• Two string inputs with gPV fuses and one combined output
• Integrated 3-pole DC switch disconnector for safe isolation
• Type 2 surge protection device (SPD) to shield against transient overvoltages
• Polycarbonate enclosure rated IP65 for outdoor wall mounting
• Screw connection terminals accept 2.5–6 mm² conductors
• Operating temperature range from -25 °C to 50 °C

Tips

Mount the box close to the PV array to keep string cable runs short. Verify that the gPV fuse ratings match your module short-circuit current and that the SPD is correctly earthed before commissioning.
