TR/PCB-1

Fuses have been used for electrical protection since the 19th century. Traditionally they were made of pieces of metal with a long wire or coil of metal placed between them. The purpose of the fuse was to act as a circuit breaker in the event of an overload to prevent the circuit from being damaged. With advances in technology, the modern fuse has evolved into a small, plastic-encased device with a replaceable element. The “TR/PCB-1” fuse, developed by TE Connectivity, is one such device and it is designed to protect circuit boards and components from damage in the event of an overload.

Application Field of TR/PCB-1 Fuse

The TR/PCB-1 fuse is designed to protect circuit boards and components in applications such as computer power supplies, communications equipment, medical devices, automotive electronics, and UPS systems. It is also used in consumer electronics, such as televisions and home entertainment systems. The TR/PCB-1 fuse is UL Recognized and meets NFPA-99 standards for hospital applications.

Working Principle of TR/PCB-1 Fuse

The TR/PCB-1 fuse is a fast-acting, lower cost alternative to traditional thermal/magnetic circuit breakers. It works by using an internal bridge that creates an electromagnetic field when current passes through it. This field forces the bridge contacts together, increasing the resistance of the circuit. If the current exceeds the fuse’s rated current, the internal bridge melts, breaking the circuit. This stops the flow of current, protecting the circuit from damage.

The TR/PCB-1 fuse is UL Recognized to a maximum voltage of 450V and a maximum current of 10A. It also has a high temperature rating of 125°C, making it suitable for high power applications. The TR/PCB-1 fuse also features a unique spring-loaded contact system, making it ideal for applications where circuit board vibration or shock may be present. The fuse can be replaced without disrupting the circuit, allowing for quick and easy field repairs.

Conclusion

The TR/PCB-1 fuse is a reliable, low-cost solution to protect circuit boards and components from overloads. The fuse is UL Recognized and meets NFPA-99 standards for hospital applications, making it suitable for a wide range of applications. The fuse’s relatively high temperature rating and replaceable element design make it an ideal solution for applications where shock and vibration may be present. The TR/PCB-1 fuse is a reliable and cost-effective solution for protecting circuit boards and components.
