Solar Connectors / Circuit function
PV Functional Connectors
An inline PV fuse connector for string-circuit protection.
- Fuse: Fuse type and rating required by the circuit
- Circuit: PV voltage and string current
- Connection: Mating connectors and room for installation and replacement
Solar connector groups
PV cable pairs, branches and fuse connectors.
Cable and panel connectors join PV wiring. T and Y branches connect parallel strings, while inline fuse connectors add a protective device to the string.

PV Functional Connectors FAQ
Product questions
Find answers about fit, wiring and product differences.
PV Functional Connectors
01Can I choose the fuse from the connector current rating?
No. The connector rating is a limit for the connection; the fuse must be selected for the PV circuit and protection requirements.
02Can the fuse connector be opened while the circuit is live?
Do not treat it as a load-break switch. Follow the isolation procedure and the installation instructions before opening or servicing the connection.
PV-30A-FUSE In-Line Solar Fuse Connector
PV-30A-FUSE In-Line Solar Fuse Connector
01Is PV-30A-FUSE a branch splitter?
No. It is an in-line fuse connector with one current path through a fuse position.
02Does the 30 A name determine the fuse required for every string?
No. The required fuse rating depends on the PV module and circuit design. The connector rating does not establish the correct protection setting.
03Is a fuse element included?
The connector has an integrated fuse holder. Fuse inclusion, type and rating depend on the ordered configuration.
