104-PR 104 Series

The 104-PR series from E-T-A is a lineup of thermal circuit breakers designed for PCB-mounted applications. These breakers come in various ratings, ranging from 0.05A to 0.6A, making them suitable for a wide range of low-voltage circuits. Each breaker features a thermal tripping mechanism, which provides reliable protection against overcurrent conditions. If you're working on projects involving small electronics, these breakers are a great choice. They're commonly used in consumer electronics, medical devices, and industrial control panels where space is limited and high reliability is essential. The PCB mounting design makes them easy to integrate into existing designs without the need for additional mounting hardware. One thing worth noting is their robustness in handling both AC and DC voltages up to 250VAC and 48VDC. This versatility allows them to be used in a variety of power supply and battery-backed systems. Engineers tend to reach for this series when they need a compact solution that can handle moderate current levels and provide thermal overload protection. These breakers are particularly useful in systems where you need to protect sensitive components from damage due to
