The Suntree Solar PV DC Fuse Link with Holder 1P 1000Vdc is a specialized electrical safety device engineered specifically for overcurrent and short-circuit protection in photovoltaic (PV) systems, battery banks, and combiner boxes .

By containing both the fast-acting fuse link and the safe-disconnect holder in a single-pole unit, it isolates faulty solar strings to prevent thermal runaway, fire risks, and catastrophic equipment damage.

Rated Operating Voltage (\(U_{e}\)): 1000V DC / 1100V DC
Number of Poles: 1P (Single Pole)
Standard Ampere Options: Typically available from 1A up to 30A / 32A for the standard compact housing (commonly stocked in 15A, 20A, 25A, and 32A variants).
Fuse Cylinder Dimensions: Standardized 10×38 mm cylindrical gPV fuse link.
Rated Breaking Capacity: 30 kA at 1000Vdc, delivering high-level short-circuit limitation.
Mounting Standard: 35mm DIN rail compatible for modular integration into distribution boards or combiner boxes.
Material & Safety: Enclosed in a 960°C flame-retardant, V0-class thermoplastic housing with an IP20 ingress protection rating.

Suntree Solar PV DC Fuse Link with Holder 1P 1000Vdc Key Operational Features

Fast-Acting gPV Performance: The internal pure silver melt element features a rapid 1–3ms time constant , breaking abnormal currents swiftly before they can flow back into sensitive solar panel strings.
Safe Disconnect under Maintenance: The holder acts as a pull-out fuse-disconnector, allowing technicians to completely isolate an individual circuit line safely. Note: The carrier text explicitly warns: Do not open under load . Always turn off the DC isolator or circuit breaker before pulling the fuse.
Robust Environmental Durability: Designed to operate efficiently across extreme temperatures ranging from -40°C to +85°C and built to withstand prolonged corrosive/acidic environments.

Suntree Solar PV DC Fuse Link with Holder 1P 1000Vdc Correct Sizing Rule of Thumb

When installing these fuses on your PV inputs, the rated current of the fuse link should be sized to 1.25 to 1.5 times the short-circuit current (\(I_{sc}\)) of your solar panel string. This buffer prevents nuisance blowing from minor daytime spikes while maintaining sharp protection against actual fault currents
