BK/S506-6.3-R Description

Short technical summary and product information.

The Eaton BK/S506-6.3-R is a 6.3A, 250VAC glass cartridge fuse with a slow blow (time-delay) characteristic. It is part of the S506 series designed to IEC 60127-2/3 standards. The fuse has a breaking capacity of 63A at rated voltage, making it suitable for overcurrent protection in circuits with moderate inrush currents.

 

The fuse features a typical cold resistance of 0.0071 ohms and a voltage drop of 54 mV at rated current. The melting I²t is 237.6 A²s, indicating a time-delay response that can tolerate temporary surges without nuisance opening. The fuse is constructed with a glass tube and nickel-plated brass endcaps.

 

This 5mm x 20mm cartridge fuse requires a holder for mounting (sold separately). It is approved by multiple agencies including BSI, CCC, CSA, cURus, IMQ, PSE/JET, SEMKO, and VDE, ensuring compliance with international safety standards. Environmental compliance includes RoHS3 and REACH unaffected status, though these are unverified.
