Functions

Core Protection Functions:

 1. Fast current-limiting protection for short circuit. Millisecond-level fault current interruption response, quickly cutting off the faulty current to prevent equipment from being burned out.

2. Stable overload protection for long-term operation. Rated current range: 1A - 630A (customizable), with precise tripping in overload conditions

3. High-voltage insulation protection. Rated voltage 3.6kV - 40.5kV, in compliance with IEC 62271-105/GB/T 15166.4 standards, without risk of breakdown.

4. Rapid arc extinction. Built-in quartz sand arc-extinguishing medium. After breaking the circuit, there is no secondary discharge, ensuring safety and reliability.

Performance and application advantages:

1. High rated breaking capacity. Breakdown capacity: 16kA - 100kA. Suitable for high-voltage equipment such as power transformers and switch cabinets. 2. Strong environmental adaptability. Stable operation within the temperature range of -40℃ to +85℃. Resistant to moisture, dust and corrosion. Suitable for both outdoor and indoor use.

3. Compact structure & easy installation. Standardized size, compatible with XRNT series fuse holders, easy for installation and maintenance

4. Visual fuse status. After tripping, the indicator pops out, quickly identifying the fault and reducing the maintenance time.

Materials Selection: Customize the production of goods by using different materials according to the customers' requests, in order to meet their needs. Including the selection of the fuse housing, the selection of the fuse element, and the selection of the fuse cap.

Color Selection: The ceramic vases are available in white and brown colors. The epoxy tubes are available in colors such as green, white, black, yellow, brown, and gray.

Packaging options: We offer products with smooth surface packaging, as well as carton packaging and wooden packaging. By default, we use packaging with the SR logo. We can also provide neutral packaging or packaging with the customer's own logo upon request.

The factory has its own component manufacturing workshop, production workshop, assembly workshop, laboratory, finished product warehouse, semi-finished product warehouse, and raw material warehouse. For the component part of our products, we produce them ourselves. We only use first-hand materials and promise not to reuse materials or use second-hand materials. Our materials (including copper, brass, aluminum, iron, tin, zinc, nickel, stainless steel, silicone rubber, and ceramics) are all purchased from official state units to ensure high quality and safety.

We have extensive export experience, including assisting customers in formulating shipping plans, facilitating customs clearance, and providing solution solutions for problems. We will help customers develop container loading plans, being able to find the most optimal solution within the limited space and weight constraints, and securing more benefits for the customers.
