The MGN15707 is a Schneider Electric Acti9 SBI 1-pole fuse-disconnector rated 50 A at 690 V AC, accepting 14 x 51 mm fuse links with GG or AM curves. It mounts on 35 mm symmetrical DIN rail and occupies 3 x 9 mm pitches (26.5 mm wide).
Fit & Integration
Screw-clamp terminals accept 2.5...25 mm² rigid or flexible cable, tightened to 3.5 N·m. The 70 mm depth and 107 mm height fit standard distribution panelboards with 35 mm DIN rail.
Rated current spans 10 A through 50 A (the unit ships at 50 A per the description), covering motor branch circuits, feeder protection, and general distribution. Fuse size 14 x 51 mm accepts standard industrial fuse links with GG (general-purpose) or AM (motor-protection) characteristics, allowing coordination with downstream contactors and overload relays.
