Frequently Asked Questions
How do I install a DROSS voltage protector?
DROSS protectors mount directly onto a standard DIN rail. Connect incoming supply to the IN terminals and your appliance circuit to the OUT terminals — no special tools required. We recommend installation by a qualified electrician.
What voltage range does it protect against?
Our adjustable voltage protectors cover an 80V–300V AC range, cutting power the instant voltage moves outside safe limits and protecting connected appliances from spikes, surges, and drops.
Does power restore automatically after a fault?
Yes. Once voltage returns to a safe range, the Auto Recovery Function reconnects power automatically — no manual reset needed.
Are DROSS products suitable for solar (PV) systems?
Yes — our DROSS Electrical range includes DC surge protective devices, DC MCBs, and PV fuse holders rated up to 1000V DC, purpose-built for solar installations.
What warranty do DROSS products come with?
