The Eaton BK/S506-V-50-R is a 50mA, 250VAC time-delay (slow-blow) glass cartridge fuse from the S506 series. It features a 5x20mm physical size with optional axial leads for through-hole mounting. The fuse is constructed with a glass tube and nickel-plated brass endcaps, designed to IEC 60127-2/3 standards.
Electrically, this fuse is rated for 50mA at 250VAC with a breaking capacity of 35A at 250VAC. It has a typical cold resistance of 9.24 ohms and a typical voltage drop of 800mV at rated current. The melting I²t is 0.0095 A²s, indicating its energy-handling capability during overload events.
The slow-blow response time makes this fuse suitable for applications with inrush currents or transient surges, where a fast-acting fuse would nuisance-trip. The 5x20mm glass cartridge format is a widely used industry standard, and the axial lead option facilitates through-hole PCB mounting.
This fuse carries approvals from multiple agencies including BSI, CCC, CSA, IMQ, SEMKO, UR, and VDE, supporting its use in a variety of equipment designs requiring recognized safety components.
