HRC fuse

HRC fuses, also known as High Rupturing Capacity fuses or cartridge fuses, are overcurrent protection devices designed to safely interrupt high fault currents in electrical power systems. These fuses consist of a ceramic or fiberglass body filled with arc-quenching silica sand, with silver or copper fuse elements calibrated to melt at precise current levels. Rated for voltages typically from 400V AC up to 690V AC and beyond, with current ratings ranging from 2A to 1250A, HRC fuses offer breaking capacities up to 120kA or more. They are available in various physical sizes including NH (low-voltage HRC) patterns, DIN types, and blade configurations, with gG (general purpose) and aM (motor protection) operating classes. Key parameters include rated voltage, rated current, breaking capacity, and I²t characteristics for selective coordination.

HRC fuses are primarily installed in main distribution boards, sub-distribution panels, motor control centers, and industrial switchgear assemblies. They are extensively used in power factor correction capacitor banks, motor starter circuits, transformer protection, and busbar trunking systems. Common sectors include heavy industry, manufacturing plants, commercial buildings, data centers, and renewable energy installations such as solar photovoltaic arrays and wind turbine converters. These fuses provide reliable short-circuit protection in environments requiring high fault current interruption without noise or gas emission.

Our HRC fuse category includes NH fuse links in sizes 00, 0, 1, 2, 3, and 4, with rated currents from 2A to 1250A. We stock cylindrical fuse links in 10x38mm, 14x51mm, and 22x58mm dimensions, as well as blade-type fuses for semiconductor protection (aR class). Key article codes follow the pattern "NH-00-100A-gG" where NH indicates the physical size, 00 the size code, 100A the rated current, and gG the operating class. Other common codes include "CYL-22x58-63A-aM" for motor protection and "BLADE-170M-630A" for high-speed semiconductor protection.

We offer express worldwide shipping with real-time pricing and stock availability on our multilingual portal. Our team of electrical engineers provides specialized technical support for fuse selection, coordination studies, and replacement recommendations. Each product listing includes detailed technical documentation with time-current curves, I²t values, and dimensional drawings to ensure correct specification and installation.
