This Littelfuse Inc. 85600001009 is a cap accessory for 5x20mm fuse holders, specifically designed to provide IP54 protection when used with compatible caps like the 856 model. It is constructed from black thermoplastic, meeting UL94VO flammability standards.
The cap is rated for a voltage of 250V and can operate in temperatures ranging from -40°C to +85°C. It is suitable for use with fuse holders compatible with 5x20mm fuses. The materials used are corrosion-protected copper alloy for metal parts and tinned terminals for solderability.
This component is designed for applications requiring enhanced environmental protection, such as in industrial or outdoor settings where dust and water ingress are concerns. Its robust construction ensures reliable performance under demanding conditions.
The rated voltage is 250V at 23°C.
The rated current is 10A (UL and VDE), 6.3A (VDE), or 12A (UL) at 23°C.
The operating temperature range is -40°C to +85°C.
With Cap 856, the protection class is IP54 according to IEC 60529.
The contact resistance is ≤5 mΩ at 20mV.
The insulation resistance is >103 MΩ at 500VDC for 1 minute.
