What are HRC Fuses?
A High Rupturing Capacity (HRC) fuse is a type of fuse designed to safely interrupt and clear very high short-circuit currents without exploding or damaging the surrounding electrical equipment.
Key Characteristics and Construction
- High Breaking Capacity: This is the defining feature of an HRC fuse. It can safely interrupt fault currents that are many times (e.g., 80 kA or more) its normal rated current.
- Construction: The fuse element (typically made of silver or copper) is enclosed within a heat-resistant body, often made of ceramic or fiberglass.
- Heat Absorption: It absorbs the heat generated by the melting element, preventing the fuse from overheating and potentially exploding.
- Time-Current Characteristics: HRC fuses come in different speeds to suit specific applications.
Authorized Distributors in Bangladesh (Dhaka):
The price of an HRC fuse varies widely based on its brand, current rating (amperage), and whether it comes with a base. For specific, high-end brands like Siemens, ABB, or Bussmann, it is best to contact their authorized distributors in Bangladesh.
