High Voltage Limiter (HVL) is a specialized utility-grade device for high voltage power distribution applications. It is typically used in place of over-current protection, thereby limiting the current that may be drawn from the system, while providing reliable, high voltage protection against arcing and thermal overload.

HVL-1/8 devices are suited for single phase or three phase applications, and are rated for a maximum operating voltage of 600 volts AC. HVL-1/8 fuses are fitted with a ceramic body in order to provide superior heat dissipation capabilities, and superior arcing protection. The HVL-1/8 is also fully insulated, so as to prevent electric shock.

The application field of HVL-1/8 devices is broad, and they are typically used in conjunction with circuit breakers and other similar protective devices. For example, HVL-1/8 fuses may be used to protect electric motors, transformers, lighting systems, and other similar systems. HVL-1/8 fuses are also well suited for applications in hazardous areas, such as those handling flammable gases, vapors, liquids, or dust particles.

The working principle of HVL-1/8 fuses is simple. When the current passing through the fuse exceeds the rated value, the fuse will "blow" and disconnect the circuit. This has the effect of limiting the amount of current that can be drawn from the system, a process known as over-current protection. Furthermore, the HVL-1/8 fuse is designed to remain in the "open" position until manually reset with a special fuse reset device.

HVL-1/8 devices are provided with an LED indicator on the front, so as to indicate when the fuse has blown. This is a useful feature, as it ensures that any problems with the circuit can be quickly identified, and the issue can be rectified in a timely manner. Furthermore, the HVL-1/8 is provided with a thermal tolerance of 85°C, which ensures that it can protect the system even in the event of high temperatures.

In summary, the HVL-1/8 is a reliable, utility-grade device that is specifically designed for high-voltage applications. It is fitted with a ceramic body for superior protection against arcing and thermal overloads. Furthermore, the HVL-1/8 provides an LED indicator on the front, which indicates when the fuse has blown. Thus, the HVL-1/8 is well suited for applications in a wide range of applications, including hazardous areas and electric motor protection.
