Schneider Electric DF141 TeSys DF Fuse Holder 1P 50 A 14x51 mm 690 V Fuse Holder

The Schneider Electric DF141 is a single-pole TeSys DF fuse carrier rated 50 A at 690 V AC/DC, sized for the larger 14x51 mm aM or gG fuse link used once control-circuit current exceeds the 10x38 mm format. Screw terminals accept 2.5-25 mm² conductors, and the carrier clips onto 35 mm DIN rail in a 26.5 mm wide housing. Short-circuit withstand is 120 kA at 400 V and 80 kA at 690 V.

Selection Notes

Step up from the 10x38 mm DF10 carriers to the DF141 once the protected load needs a fuse rated above 32 A but a single pole is still sufficient, such as a larger single-phase control transformer primary. The 14x51 mm fuse body carries more thermal mass than the 10x38 mm size, which is why the line jumps straight to 50 A rather than offering intermediate steps in the smaller housing. Screw terminals rather than screw-clamp terminals suit the heavier 2.5-25 mm² cross-sections typical at this current level.
