Fuse Holder Switch STI 2P 500V

These Acti9 STI isolating fuse holders are low voltage fuse disconnectors. They are used for commercial and industrial applications requiring a high breaking capacity. It has a 2P pole, a rated current of up to 25A, and a gG or aM fuse curve with a 10.3mm x 38mm fuse cartridge type. It can be mounted on a DIN rail for modular installation. The general-purpose fuse (gG fuse) provides protection against overloads and short circuits. The aM fuse for motor applications provides short-circuit protection (protecting loads with a high peak current). It features an IP20 protection rating at its terminals, making IP40 in a modular enclosure. A snap-on marker is visible on the front face or the downstream terminal to identify the presence of the fuse. An optional 230 V neon indicator light shows that the fuse has blown (off during normal operation and on in red after the fuses have blown). The device comes with a captive fuse holder and an additional box for a spare fuse. Its lever can also be padlocked.
