DNH18 Fuse Switch Disconnector with a Unique Structure for Quick and Convenient Wiring, Can Fully Replace the Top-tier Brands in the Industry
The DNH18 fuse switch disconnector is designed to provide a safe method for disconnecting power in a circuit while offering additional protection with fuses. When the current exceeds a specified value for a certain period, the fuses generate heat, causing the fuse switch to trip and further aiding in circuit disconnection. As a current protector, they achieve protection and safeguarding effects and can largely mitigate potential safety hazards in daily circuit wiring systems.
Compared to similar products, the DNH18 fuse switch disconnector boasts absolute advantages in performance. In fact, it can fully replace the top-tier brands in the industry.
DNH18 fuse switch disconnector holds 12 patents and is designed with many key features:
1、Unique structure for quick and convenient wiring
DNH18 fuse switch disconnector features a fixed flip cover, making wiring convenient. The flip cover at the bottom of the DNH18 fuse switch disconnector can be opened and fixed upwards during construction wiring, making it very convenient. After wiring, closing the cover can cover the cable connection area, providing both aesthetics and convenience.
2、High-performance standards for safety and reliability
DNH18 fuse switch disconnector has added heat dissipation groove channels on the side to enhance heat dissipation, resulting in excellent temperature rise performance that surpasses national standards. The base also includes protrusions to protect copper components, ensuring reliable conductivity and preventing virtual connections.
3、Unique design for excellent user experience
DNH18 fuse switch disconnector offers two operation modes, single-phase individual operation, and three-phase synchronous operation, to better meet customer needs. The installation and removal of the switch fuse are simple and fast, requiring only horizontal movement of the top red slider to fix and unlock the fuse core.
4、No need for calculation, simple installation
DNH18 fuse switch disconnector eliminates the need for calculation during installation. The base of the product has spacing blocks that, when combined, create a 5mm electrical spacing, making installation quick and convenient and saving installation costs.
5、Flexibility
Whether installed indoors or outdoors, the DNH18 Vertical fuse disconnector can provide the same functions and can be customized according to the specific requirements of the power system. It has two installation methods: hanging and fixed, and two opening methods: integrated and split, allowing you to choose the one you need according to your requirements.
6、Safety and durability
This product is of high quality and standards, certified with CE, CB, TUV, CCC, and other certifications. It adopts purple copper contacts, and the shell material is nylon, achieving V0 flame retardant rating. The screw fittings use toothed bolts with a self-locking function, ensuring quality and peace of mind.
Additionally, the DNH18 fuse switch disconnector can be optionally equipped with a fuse monitor, which can emit a signal when the fuse is blown and can also realize remote monitoring.
Similarly, the DNH18 fuse switch disconnector has good abrasion resistance, with the number of switch operations reaching over 200 times underpowered conditions. This durability ensures long-term stability and low maintenance costs of the switch.
Application scenarios
Industrial production lines
Large-scale mechanical equipment
Power transmission and distribution systems
Renewable energy systems such as wind and solar
power generation
Choosing the right bar-type isolation switch is crucial for any power system that requires high safety and efficiency. By using the DNH18 fuse switch disconnector, not only can system safety and reliability be improved, but also great convenience can be provided during maintenance.
Whether your needs are for industrial applications, commercial buildings, or specific engineering projects, high-quality bar-type isolation switches are an indispensable choice.

GRL DNH7 Fuse Switch Provides Safe Protection for TBEA‘s JP Box
Born to Be Safe: GRL‘s Fuse Switch Provides Safe Protection for TBEA, a Leading Power Transmission and Transformation Company. TBEA faced a temperature rise issue in a JP box project using an international brand fuse switch. GRL offered a solution by replacing the fuse switch with its DNH7 model, modifying the switchgear layout, and using a low-power fuse. The final temperature rise was within the qualified standard.
State Grid‘s Power Distribution Upgrade used GRL‘s Fuse-links, Switches, and Busbar Systems
State Grid Corporation of China, the largest grid builder and operator in China, uses GRL products including fuse-links, isolator switches, and busbar systems for safer power distribution boxes. GRL provides a range of fuse coverage for different currents and adopts derating treatment in plateau areas. Toughened DMC materials are used for fuse disconnectors in complex environments. GRL also assisted in launching an integrated solution for transformers and integrated distribution boxes, with busbar systems available in different sizes for energy distribution.
GRL Supplied the Solar Panel Combiner Box and DC Fuse Box for Photovoltaic Power Generator System
This is the first time that GRL’s DC isolator switch and DC fuse have appeared in the South American market. GRL’s 400A switch disconnector and DC fuse can adapt to the use environment in many countries and meet the usage habits of the global photovoltaic market.
GRL Provides Fuses, and Fuse Switches in GW155 Wind Turbines
GRL participated in Goldwind‘s 3 million kW wind power poverty alleviation project in Inner Mongolia, China, providing fuses and fuse switches for the GW155-4.5MW wind turbines. The wind power system includes wind turbines, overhead lines, transformers, and grid boxes, with GRL‘s 160A fuse switch disconnector applied to ensure reliable protection. The GW155-4.5MW wind turbine has maintained an availability rate above 99.7%.
GRL Provides Fuses and Fuses for BYD AUTO Energy Storage Battery Production Line
GRL provides fuses, fuse bases, and fuse switches for BYD’s Shenzhen production plant. The equipment damage rate of BYD’s Shenzhen production line decreased by 5% due to the timely blowing of fuses.
GRL Adopts DNH18 Fuse-type Isolating Switch, with a Special Diversion Groove on the Side, to Create a Safe Distribution Box
Shanghai Zhixin, China‘s largest transformer supplier, faces a temperature rise issue in cable branch boxes. GRL Electric offers a solution with its DNH18 fuse-type isolating switch, featuring a special diversion groove that quickly guides hot air out of the box, ensuring safety. The switch also passes the 10KA short-time withstand current test with a special low-power fuse that fuses quickly without ceramic explosion. GRL and Shanghai Zhixin have a long history of cooperation, with GRL‘s DNH18 switches widely used in power grid projects in Shanghai, Hangzhou, and Suzhou.
