Product Description

The Leyden AC & DC Surge Protective Device Combo is a complete protection solution for modern electrical and solar power systems. This combo includes both AC SPD and DC SPD, ensuring protection across the entire power flow—from solar panels to inverter output and main distribution board.

The AC SPD (320VAC) protects household and industrial electrical circuits from transient surges, while the DC SPD (600VDC) safeguards solar panels, inverters, and battery systems from lightning and switching surges.

With a 20kA nominal discharge current and 40kA maximum surge capacity, these devices provide robust and reliable protection. The visual status indicators allow quick inspection, while the DIN rail mounting design ensures easy installation.

Perfect for solar PV systems, homes, commercial buildings, telecom systems, and industrial applications, this combo offers a complete surge protection solution in one package.
