Cylindrical fuse for solar power plants 10x38 mm – 15A, 1000V DC, 33kA, gPV

Cylindrical gPV fuse 10x38 mm designed for the protection of solar power plants, photovoltaic modules, and DC circuits against short-circuit and overcurrent. This is a 15A, 1000V DC fuse with a 33kA breaking capacity, suitable for installation in standard 10x38 mm fuse holders used in PV protection panels and solar system circuits.

Main idea:
This fuse is designed for photovoltaic DC circuit protection, where reliable disconnection of hazardous current in the event of a short-circuit or overcurrent is required. The gPV utilization category means that the fuse is specifically tailored for solar power plant circuits operating at high DC voltages.

Current
15 A

Voltage
1000 V DC

Class
gPV

Size
10x38 mm

Operating principle

The cylindrical PV fuse is installed into a fuse holder and connected within the direct current circuit. During normal operation, the fuse conducts current; however, in the event of an overcurrent or short-circuit, the internal element of the fuse melts and breaks the electrical circuit.

In solar power plants, such fuses are used to protect PV module circuits, DC protection panels, inverter inputs, or other DC circuits. gPV class fuses are adapted to the specifics of photovoltaic systems, which may feature high DC voltage and specific short-circuit conditions.

Why do PV systems require a special gPV fuse?
Solar power plants operate on direct current, so protection devices must be selected specifically for DC circuits. The gPV fuse is designed for photovoltaic circuits and helps safely disconnect dangerous overcurrents or short-circuits, whereas standard AC fuses are not suitable for such applications.

Where is it used?

In solar power plants – for protection of PV DC circuits against short-circuit and overcurrent.
In PV module circuits – protecting individual module sequences or strings as per the project.
In DC protection panels – mounted together with 10x38 mm fuse holders.
In PV inverter inputs – for additional DC protection, if provided for in the schematic.
In battery or energy storage system DC circuits – only if such use is permitted by the specific project and component parameters.

Practical installation example

For example, the fuse is installed into a 10x38 mm DC fuse holder in the solar power plant protection panel. A separate gPV fuse can be selected for each PV module circuit, with the current and voltage ratings corresponding to the specific system project.

Once the fuse trips, the circuit is broken, and the fuse must be replaced with a new one of the same (or project-specified) nominal current and voltage rating. Before replacement, it is mandatory to safely disconnect the DC circuit and ensure that no dangerous voltage is present.

Pros

1000 V DC rated voltage – suitable for high-voltage solar power plant DC circuits.
gPV utilization category – specifically adapted for photovoltaic circuits.
33 kA breaking capacity – high level of protection in the event of a short-circuit.
Compact 10x38 mm format – fits standard fuse holders.
Copper contacts – good electrical conductivity and reliable connection.
Flame-retardant insulating body – additional safety aspect in the electrical cabinet.
Suitable for PV protection panels – convenient solution for protecting solar module circuits.

Cons / limitations

Not suitable for AC systems – this is a fuse intended for DC photovoltaic circuits.
Fuse holder required – the fuse must be installed in a compatible 10x38 mm DC holder.
Single-use – once the fuse trips, it must be replaced with a new one.
Need to precisely select current – 15 A must match the parameters of the specific PV circuit.
Replacement must be safe – dangerous voltage may remain in DC circuits even after disconnecting part of the system.

Safety and installation notes

A PV fuse is a direct current protection component; therefore, its selection and installation must be performed according to the solar power plant project, PV module parameters, inverter data, and electrical safety requirements.

Installation must be performed by a qualified electrician or solar power plant installer experienced with DC circuits.
Use only in appropriate DC fuse holders adapted for 10x38 mm and 1000 V DC fuses.
Do not use in AC circuits if the fuse is intended only for photovoltaic DC systems.
Current must be selected according to the project – an incorrect fuse rating can lead to insufficient protection or nuisance tripping.
After tripping, the fuse must be replaced with a new one – the fuse is not resettable.
DC circuits can be dangerous – before replacement, it is mandatory to safely disconnect the system and check the voltage.
