The Eaton BK1/S506-250-R is a time-delay (slow blow) glass tube fuse designed for overcurrent protection in electronic circuits. It is rated for 250 mA at 250 VAC and provides a breaking capacity of 35 A at rated voltage, making it suitable for applications where brief inrush currents occur.
The fuse features a 5.20mm x 20.00mm physical size and uses nickel-plated brass endcap construction. It requires a holder for mounting, with optional axial leads available. The typical cold resistance is 0.640 Ω and the typical voltage drop at rated current is 270 mV. The melting I²t is 0.265 A²s.
This component is designed in accordance with IEC 60127-2/3 standards and holds multiple international safety approvals including UL, CSA, VDE, SEMKO, BSI, IMQ, CCC, and PSE/JET. It is RoHS3 compliant and has an MSL rating of 1 (unlimited).
