Type 1+2 DC Surge Protection

The Type 1+2 SPD Surge Protective Device 20–40kA 1200V DC 2-Pole (LKX-T1T2-DC) delivers combined Class I + Class II surge protection for high-voltage DC and photovoltaic power systems, providing robust defence against direct lightning currents, induced surges, and transient overvoltage. Designed with a GDT + high-energy MOV hybrid protection circuit, it offers high lightning impulse capacity, ultra-fast response, thermal disconnection protection, and stable long-term operation for solar PV arrays, combiner boxes, central/string inverters, large-scale PV plants, battery storage systems, and 1200V DC distribution networks.
