OFPAL480.X Application Field and Working Principle

OFPAL480.X is a block-type fuse used in electrical installations and power distribution systems. It consists of an aluminium enclosure containing a positive temperature coefficient resistor (PTCR). This PTCR acts as a resistance that is inversely proportional to the current flowing through it. The power of the fuse depends on the size and shape of the enclosure. Due to its shape, the fuse dissipates heat quickly and can withstand high electrical loads.

The primary use of OFPAL480.X is as an overvoltage protection device in circuits carrying low-voltage currents. It is designed to break the circuit when the current exceeds the specified maximum. The fuse element also provides an additional safety measure by limiting the current to the maximum to protect against inadvertent application of higher voltage or current.

The working principle of the OFPAL480.X is that it limits the current in the circuit to a predetermined maximum. This maximum may be set by the user or preset by the manufacturer. When the current rises above this maximum, the fuse element melts, allowing the current to pass through it temporarily. The current then drops to a safe level, and the circuit is isolated. The fuse element also has a secondary safety device that prevents the current from rising again after the threshold has been exceeded.

The OFPAL480.X is a highly reliable and cost-effective protection solution for low voltage systems. It is reliable, as it is designed to withstand short-term overloads and surges. In addition, it is cost-effective, as it eliminates the need for additional overvoltage protection components or devices. It is also easy to install and maintain, as it is designed for quick, easy installation and maintenance.

The OFPAL480.X is an effective and reliable fuse for low voltage electrical installations. It provides reliable protection for overvoltage loads and is easy to install and maintain. Its cost-effectiveness and versatility make it an ideal choice for many applications.
