ABB Entrelec 1SNA115663R2300 | M4/8.SFD Fused Terminal Block, 24V LED Blown-Fuse Indicator, 8mm Spacing Lot of 16

The 1SNA115663R2300 is a single-level fused terminal block featuring a "lever-action" fuse carrier. This design allows for the safe isolation and replacement of fuses without removing the wiring. The "SFD" designation indicates it is equipped with a 24V LED blown-fuse indicator, which draws a tiny amount of leakage current to illuminate the LED once the fuse opens. It is the gold standard for protecting 24V DC/AC control circuits in automation panels.
