The “gG” designation isn’t arbitrary—it follows international standards (such as IEC 60269) that define fuse performance and operation. The first letter “g” indicates the gross breaking capacity, meaning the fuse can safely interrupt currents up to its specified breaking capacity without causing damage to the surrounding system or posing a safety hazard. The second letter “G” (often written as lowercase “g” in some standards, but the meaning remains consistent) stands for general purpose, signifying that these fuses are designed to protect against both overcurrents and short circuits in a wide range of electrical installations.
Key Features of low voltage fuses NH100 gG-gL
-
Broad Current Rating Range: They’re available in a wide range of current ratings (from a few amps to several hundred amps), making them suitable for everything from small household appliances to large industrial motors.
-
High Breaking Capacity: As “g” class fuses, they have a high breaking capacity—meaning they can safely interrupt even large short-circuit currents (often up to 120 kA or more, depending on the model). This is crucial in industrial settings where short-circuit currents can be extremely powerful.
-
Selective Protection: gG fuses have a time-current characteristic (TCC) that allows them to coordinate with other protective devices (like circuit breakers or smaller fuses).
-
Durability and Reliability: They’re built to withstand harsh conditions, including temperature fluctuations, vibration, and chemical exposure (in industrial environments).
Common Applications of low voltage fuses NH100 gG-gL
-
Residential and Commercial Buildings: In distribution boards (consumer units), gG fuses protect lighting circuits, power outlets, and small appliances. They’re often used in older buildings or as a cost-effective alternative to circuit breakers.
-
Industrial Machinery: They protect motors, pumps, conveyors, and other industrial equipment from over currents and short circuits. Their high breaking capacity makes them ideal for heavy-duty applications.
-
Power Distribution Systems: In low-voltage switchgear and distribution panels, gG fuses safeguard the main power supply and branch circuits, ensuring stable power delivery to critical systems.
-
Renewable Energy Systems: They’re used in solar PV systems and small wind turbines to protect inverters, batteries, and wiring from current surges—an essential feature in systems where power output can fluctuate.
