Weidmuller offers versions of the WSI fuse terminals
with low 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, full wave rectified 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.

WSI Fuse Terminals with Low Current Status Indication
WSI 6 LD
with LED indicator for
DC or AC voltage
WSI 6 LD and WSI 6/2 LD
WSI 6/2
with LED for inch fuses VAC/VDC
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.
