PCB-1-1/2-R

The PCB-1-1/2-R is part of a larger family of fuse products known as over-current protection devices. Generally speaking, over-current protection devices are designed to protect electrical equipment like computers, appliances, and industrial automation systems, from damage due to short-circuits, overvoltage, and ground faults. The PCB-1-1/2-R is a type of fuse specifically designed for low voltage (<1000V) applications.

The PCB-1-1/2-R is packaged and sold as a plastic cylinder containing two spring-loaded metal arms, each with a ceramic disc riveted to their tips. The discs are rated with a specific maximum allowed current or amperage. When an overload occurs in a "protected" circuit, causing the current to exceed the maximum allowed, the high heat generated by the excess current causes the ceramic discs to burn away, disconnecting the flow of current and protecting the circuit from damage.

The PCB-1-1/2-R is amperage-rated from 4A - 12A. It is designed for use in the Automotive, Marine, and RV industries. Additionally, it can be used in residential and industrial electrical applications such as circuit boards, electric motors, and pumps, and other similar low voltage (<1000V) applications.

The PCB-1-1/2-R offers several advantages over other fuse types. First, it is UL-certified, ensuring its compliance with safety regulations. Secondly, its high dielectric strength helps it withstand thermal and electrical stress in high temperature environments. Lastly, its low response time to a sudden current spike makes it an excellent choice for protecting sensitive equipment from damage caused by sudden overloads.

The PCB-1-1/2-R is easy to install and relatively inexpensive. It is compatible with most terminal boards and electric panel boxes, and can be used in parallel with other fuses of the same amperage rating. Fuses must be matched to the equipment and application they are being used to protect, so it is important to choose the right fuse for the job. The PCB-1-1/2-R is ideal for low voltage applications and offers protection against sudden current spikes.

In conclusion, the PCB-1-1/2-R is a type of fuse specifically designed for low voltage (<1000V) applications. It is UL-certified, has a high dielectric strength, and has a low response time to a sudden current spike, making it an excellent choice for protecting sensitive electrical equipment from damage. Additionally, the PCB-1-1/2-R is easy to install, relatively inexpensive, and can be used in parallel with other fuses of the same amperage rating.
