Eaton Radial Fuse 4A Current Rating 250V AC Time Delay SR-5-4A-BK

Eaton SR-5-4A-BK radial fuse offers efficient overcurrent protection with a 4A current rating and 250V AC operating voltage. This fuse features a time delay characteristic that allows transient current surges without opening, essential for protecting sensitive circuits without nuisance interruptions. It is designed with radial leads measuring 1mm in diameter and 4.3mm in length, suitable for through-hole mounting and secure soldered wire connections.

The fuse has a robust breaking capacity of 40A, effectively limiting the energy from fault currents during severe short-circuits. Its compact dimensions - 7.37mm in length and 8.5mm in diameter - facilitate integration into tight electronic assemblies. Furthermore, it operates reliably over a broad temperature range from -40°C to +125°C, ensuring suitability for demanding industrial environments.

Conforming to internationally recognized standards including VDE, IEC 60068-2-20, RoHS, PSE, and IEC 60127-3, the Eaton SR-5-4A-BK fuse guarantees safety and performance excellence. Typical applications include control panels in factory automation systems, power supplies for industrial electronics, motor drive circuits requiring inrush current tolerance, domestic appliance safety circuits in manufacturing, and prototype boards demanding compact, reliable fuse protection.

The time-delay (slow-blow) behavior reduces unnecessary disruptions in circuits with high startup currents by allowing brief spikes to pass while interrupting sustained faults. Radial lead design simplifies mounting and replacement, supporting secure and robust mechanical retention.

Choose Eaton SR-5-4A-BK fuse for reliable, standardized, and durable circuit protection across a variety of industrial, commercial, and laboratory applications. 4A current rating protects electrical circuits while allowing transient surges.

Time delay feature prevents nuisance tripping during inrush currents. Radial lead orientation with 1mm diameter leads enables through-hole mounting. Breaking capacity of 40A safely limits fault energy during short circuits.
