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.
Features:
• 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.

Note:
Voltage is disconnected by opening the disconnect lever. If the
fuse of the LED variants is defective, the downstream circuit is still
under current, since low-level current is still flowing via the LED.
