Last updated: October 2026
Solar fuse connectors with integrated DC fuses for overcurrent protection of PV strings, rated 1000 V/1500 V DC with current ratings from 15 A to 30 A.
A fuse connector puts string overcurrent protection directly on the DC cable, in a weatherproof housing that mates with the standard PV connector interface. It replaces a separate fuse holder and its enclosure, which removes two connection points and the extra cable length between them — both common sources of voltage drop and water ingress on a rooftop array.
The range covers both common fuse sizes. F4C-200-1085 and F4C-201-1085 take the 10.3 × 85 mm fuse and are rated 1500 V with 1 to 30 A fuses; F4C-212-1038 takes the compact 10.3 × 38 mm fuse at 1000 V/1100 V TÜV. All three are IP68 in the mated condition with contact resistance below 0.5 mΩ.

Frequently asked questions
How do I size the fuse for a string?
The fuse must carry the string current continuously and still open on a fault. Work from the module Isc: the usual rule is to rate at 1.25× Isc and stay within the module series-fuse rating, then check that the fuse holds at the highest expected ambient. Oversizing for temperature is the usual mistake — it delays clearing on a genuine fault.
Which fuse size should I choose, 10.3 × 85 mm or 10.3 × 38 mm?
The physical size follows the voltage and breaking capacity you need. The 85 mm body carries the 1500 V rating; the compact 38 mm body is rated 1000 V/1100 V. If the array runs at 1500 V DC, use the 85 mm version.
Does the fuse connector meet the connector standard as well?
The mated interface follows the same PV connector construction as the rest of the range, and the fuse element is a separate certified component. Check both: the connector standard covers the housing and contact, while the fuse has its own rating for voltage, current and breaking capacity.
