OSFE030.VP Application Field and Working Principle

Fuses are one of the most important components used in electrical protection and safety systems today. The OSFE030.VP Fuse is an important part of the comprehensive fuse protection systems offered by Cooper Bussmann. OSFE030.VP Fuses are used in both residential and commercial applications.

Cooper Bussmann’s OSFE030.VP Fuses are designed to protect against surges, short-circuits, and other electrical problems. This type of protection device helps ensure the safe operation and maintenance of electrical systems, preventing hazardous situations and protecting equipment from damage. OSFE030.VP Fuses are ideal for commercial and industrial settings due to their compact size, great overload protection, and flexibility when it comes to installation.

OSFE030.VP Fuses: Working Principle

OSFE030.VP Fuses work on the principle of thermal energy conversion. When the fuse is exposed to an electrical current that is higher than its rated value, the fuse element rapidly heats up due to the high temperature of the current. This causes a rapid increase in the internal temperature of the fuse and its corresponding varistor. When the temperature level reaches above a certain threshold, the fuse will mechanically blow apart, breaking the electrical circuit.

When this happens, the current is interrupted and the fuse is no longer able to sustain the current, shutting off the power supply. This helps protect the circuit from further damage or overloads which can cause equipment to malfunction or even catch fire. The fuse must be replaced after the fuse has been blown apart in order to restore the power supply and resume normal operation.

Application Field

OSFE030.VP Fuses are typically used in residential and commercial control systems and equipment. They are often used to protect motors, circuit breakers, transformers, switchboards, and other circuits and systems from electrical overloads. They are also used in emergency lighting systems and power supplies for communication and critical infrastructure equipment.

The UL Classification for these Fuses, UL 977 File # E96988, specifies this type of device as being suitable for industrial overload power failure protection. It is also suitable for protecting power ratings of 20A to 50A in 125V, 160V, 250V, or 480V single phase or three phase installations.

These Fuses also meet the UL Class H fusing standard for applications up to 600V, giving them a wider range of applications than other types of fuses. These Fuses can handle up to 200A in power ratings of 125V to 600V, making them suitable for a variety of wiring and electrical systems. In short, OSFE030.VP Fuses protect circuits and equipment from electrical overloads and associated hazards.
