PVM-7

PVM-7 fuses offer over-current and short-circuit protection for a wide range of electronics and electrical equipment. They are an excellent choice for protecting robust systems intended for long-term use, such as industrial or utility-grade power systems. The PVM-7 fuse offers reliable protection with a lower time current curve then most other types of fuses, so it can provide better protection from short bursts of large overload current.

The PVM-7 fuse utilizes two coil-wrapped, highly conductive metal strips that are wired in series. This allows the fuse to rapidly sense current changes and quickly respond to overloads caused by short circuits or excessive current. As the current through the fuse is increased, the heat generated by the current flow causes the coil-wrapped strips to heat up and physically expand. This forces the contacts of the fuse open, breaking the connection and stopping the flow of electricity.

The PVM-7 fuse is rated from 0.1 to 35 amps and is available in volage ranges from 0.3 to 600 volts. The PVM-7 fuse’s wide tolerance for voltage makes it suitable for AC and DC applications. It is valued for its ability to quickly and accurately sense and react to short-circuit or overloads. The fast-acting feature of these fuses keeps them from burning out when the circuit is opened, ensuring reliable performance and safe operation.

Apart from its overcurrent and short-circuit protection capability, the PVM-7 fuse differs from other types of fuses in that it only covers electronic and electrical equipment. Although the official voltage ranges of the PVM-7 fuse are from 0.3 to 600 volts, the fuse is rated to safely handle much higher voltages when required. Available thread mounting sizes range from 0.25 inch to 1 inch and the fuse accommodates an operating temperature range of -55°C to 125°C.

The PVM-7 fuse is ideal for highly demanding applications that require fast-acting protection from short circuits and over-current situations. Industrial and utility-grade power applications, such as power distribution systems, industrial control systems, and medical diagnostic equipment, benefit from the fast-acting protection of the PVM-7 fuse. High-powered and sensitive computers, such as those used in large-scale offices and data centers, are also best protected by the PVM-7 fuse.

The PVM-7 fuse has quickly become one of the most preferred fuses for automotive and industrial applications. It offers reliable protection and is available in a variety of sizes and ratings to meet the needs of any given application. The fast-acting properties of the PVM-7 fuse are also a major benefit for those looking for reliable protection for sensitive, powerful, and long-term power systems.
