Fuse link - NH0 gPV 100A/1000V DC - for protection of photovoltaic PV / DC installations 004110387

Photovoltaic installation safety – NH0 gPV 100A/1000V DC fuse link

The NH0 gPV 100A/1000V DC fuse is a component dedicated to protecting photovoltaic (PV) installations operating in direct current (DC) circuits. It provides effective protection against the effects of short circuits and overloads, which is crucial for the reliable and safe operation of the system. Its gPV characteristic has been specially developed with the specific requirements of PV installations in mind, taking into account potential loads associated with the operation of solar panels.

Protection and application

This fuse is designed to protect DC circuits in photovoltaic systems. The gPV characteristic allows for a quick response to a short circuit, minimizing the risk of damage and fire, while tolerating short-term current surges that may occur during start-up or changes in sunlight conditions. The top indicator facilitates visual control of the fuse status – whether it has blown and needs to be replaced.

Key features and benefits

• Rated current 100A: Provides adequate protection for installations with a power of up to 100A.
• Rated voltage 1000V DC: Suitable for operation in installations with high DC voltage, typical of photovoltaic systems.
• gPV characteristic: Specifically designed to protect photovoltaic installations from the effects of short circuits and overloads. Allows for a quick response to a failure, minimizing the risk of damage.
• Top indicator: Enables quick and easy visual inspection of the fuse status without the need for disassembly.
• Complies with IEC 60269-6 standard: Guarantees compliance with stringent safety and quality standards.
• Rated breaking capacity 20kA: High short-circuit breaking capacity ensures safety even in the event of serious failures.
• No metal insulated grips (IMGL): IMGL-free design simplifies installation and replacement of the fuse.

Technical parameters

The NH0 gPV 100A/1000V DC fuse is characterized by a time constant L/R of 2 ms and a breaking Joule integral of 5,280 A²s, and a pre-arcing of 1,110 A²s. The power loss Pd is 21 W, which affects the energy efficiency of the system. The weight of a single fuse is 0.29 kg, and its dimensions are 29 mm x 124 mm x 60 mm.
