Product Announcement from Weidmuller
Weidmuller offers versions of the WSI fuse terminals
with low leakage current blown fuse indication (BFI).
The BFI circuit is located in parallel with the fuse so
that a current goes through the indicator only when
the fuse blows. As this current is an unwanted off-state
leakage current it is important that the level be kept to
an absolute minimum. Weidmuller's BFI circuits draw
no more than 500μA - not enough to pose a safety
hazard or falsely energize PLC or DCS digital inputs.
• WSI 6 LD for 5x20mm fuses, just 8mm wide
• WSI 6/2 LD for 1¼" x ¼" fuses, 12mm wide
• Moulded from UL 94-V0 Wemid material
• 35mm DIN rail mounting
• Non-polarized, bi-polar LED circuit with less than
500μA leakage at nominal voltage as per CSA
Standard C22.2 No. 39 Fuse Holder Assemblies
and UL Standard 512 Fuseholders.
