About Surge Protection & Fuses

Surge protection devices and DC fuses for solar PV strings, inverters and battery banks. This range covers Type 2 SPDs rated from 150V up to 1000V DC for protecting panel strings and inverters, plus NH fuse switch disconnectors and fuses for battery and DC circuit protection.

Installers use these to guard PV systems against transient overvoltage and to isolate faults safely. Options are differentiated by voltage rating, pole configuration and current rating, including NH fuse switches rated up to 630A, so you can match the device to the string voltage and circuit current on the job.
