20-piece kit of RXEF polymer self-recovery fuses (PPTC) Models: RXEF005 through RXEF500, including RXEF030 and RXEF050 Material: polymer-based PPTC Voltage compatibility: designed for 60 V and 72 V DC systems Current range: 0.05 A to 5 A (example: RXEF030 = 0.3 A at 72 V) Key benefits — why you need this product Provides reliable, resettable overcurrent protection for high-voltage, low-current DC circuits, preventing wiring and component damage without replacing fuses after a fault. Saves time and maintenance costs by automatically resetting once a fault is cleared, making the protection reusable across many cycles. Flexible model range in a single 20-piece pack lets you match protection precisely to different circuit currents and designs. Function and standout attributes Self-recovery operation: PPTC material limits current during faults and returns to normal conduction after cooling and fault removal. Wide model coverage: RXEF005–RXEF500 covers 0.05 A to 5 A, enabling precise selection for sensitive inputs and downstream electronics. Voltage-rated for 60 V and 72 V DC applications, ensuring compatibility with common higher-voltage battery and power systems. Low leakage in normal operation and fast response to overcurrent reduce risk while maintaining circuit performance. Compact form factor suitable for PCB mounting or inline use; integrates easily into boards and modules. Durable cycling capability for repeated protection events in demanding environments. Practical applications Electric vehicles and light electric mobility: battery packs, DC-DC converters, and accessory circuits in 60–72 V systems. Photovoltaic systems: solar charge controllers and DC-link protection for PV inverters and arrays. Industrial and backup power: control panels, UPS modules, and low-current protection in industrial electronics. Package contents and selection note Kit contains 20 self-recovery fuses from the RXEF family, offering a balanced mix of ratings to match common 60–72 V system needs. Use the RXEF model corresponding to the circuit hold/trip requirements; for reference, RXEF030 is rated at 0.3 A at 72 V. Reliable, compact, and reusable protection for higher-voltage, low-current DC systems using polymer PPTC technology.
