As a professional manufacturer of 3.6KV HRC Current-limiting Fuses, SARAH Electric possesses advanced production lines and a strict quality control system. Its products have obtained ISO9001 quality management system certification and have been exported to markets in Southeast Asia, the Middle East, South America and Africa. The company has established long-term cooperative relationships with the State Grid, the Southern Grid and many large industrial enterprises. The products have been operating stably in key national projects and overseas projects, and have won widespread praise from customers for their high reliability and excellent service.
The SARAH Electric brand 3.6KV HRC Current-limiting Fuse is designed with high breaking capacity (HRC), with a rated current range of 0.5A to 200A and a breaking capacity of up to 50kA. It is compatible with mainstream models such as XRNP1, XRNP2, and XRNT1. The fuse tube is made of ceramic or epoxy resin insulating materials, with high-purity quartz sand filled inside to ensure rapid arc extinction and long-term operational stability.
The product has passed IEC 60282-1 and GB/T 15166.2 standards certifications and has been supplied in large quantities to the State Grid, new energy power stations, and overseas industrial projects.

Core Features
The rated breaking current is as high as 50kA, which can effectively cut off system short-circuit faults.
The 3.6KV HRC Current-limiting Fuse offers multiple rated current specifications, enabling it to coordinate and cooperate with upstream and downstream protection equipment.
The fuse tube is made of high-strength ceramics or epoxy resin, which is resistant to high temperatures and corrosion.
It is filled with high-purity quartz sand inside to ensure the rapid extinction of the electric arc.
The HRC current-limiting fuse is made of high-purity copper material, with low contact resistance and small temperature rise.
Application
Suitable for main protection at the incoming side of 10kV, 20kV, and 35kV oil-immersed/dry-type transformers.
Limiting current fuses for indoor 12kV/24kV/36kV high-voltage cabinets.
Short-circuit protection for capacitor banks, voltage transformers, and dry-type reactors.
Simple, low-cost, and highly reliable 3.6KV HRC Current-limiting Fuse equipment for mines, construction sites, etc.
FAQ
Q: In which types of equipment are 3.6 kV HRC current-limiting fuses installed?
A: Common installation locations include metal-clad switchgear, motor control centers (MCCs), transformer protection panels, and capacitor panels.
When installing, it is necessary to verify the fuse dimensions, mounting method, contact spacing, and insulation clearance.
Q: Why is the breaking capacity of a 3.6 kV HRC fuse important?
A: When a short circuit occurs, the fault current can reach tens of kiloamperes (kA). If the breaking capacity is insufficient, the arc cannot be extinguished, and the fuse body may be damaged, potentially escalating the fault.
Therefore, it is essential to ensure that the Rated Breaking Capacity is greater than or equal to the system's short-circuit current.
Q: Can this device be used for motor starting protection?
A: Yes, but proper selection and matching are required.
Motor protection requires consideration of the starting duration, starting current curve, locked-rotor current, and running current. Typically, a dedicated motor protection fuse should be selected.
