What is DNH18 fuse switch disconnector?

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.
