Schneider Electric Acti9 STI Fuse Disconnector A9N15646 - 1P+N 25A
Schneider Electric Acti9 A9N15646 is an STI fuse disconnector. It holds a 10.3 x 38mm fuse and lets you isolate a circuit by opening the fuse carrier. It has 1 pole plus neutral and is rated up to 25A at 500V AC. You can use gG fuses for general overload and short circuit protection, or aM fuses for motor circuits. The carrier is captive, so it cannot get lost, and there is a spare fuse housing inside. A clip-on marker shows that a fuse is fitted. An optional 230V neon indicator can show when a fuse has blown. The toggle can be padlocked for safe isolation. Fuses are not included, so you can choose the rating you need, from 2A to 25A. The unit is 18mm wide and mounts on a DIN rail. It is used in commercial and industrial panels that need high breaking capacity.
