Weidmüller 1014100000 WSI 6/2/LD Fuse Terminal Block – 6.3A, 10-36V AC/DC, LED Blown-Fuse Indicator, 5x20mm

The WSI 6/2/LD is a pivoting-lever fuse terminal designed for $5\text{x}20\text{mm}$ glass or ceramic cartridge fuses. It combines a standard feed-through terminal with a safe, finger-protected fuse holder. The built-in low-voltage LED circuit (10-36V) bypasses the fuse; when the fuse is intact, the LED is off, but once the fuse blows, the current flows through the indicator, lighting it up to signal a fault.
