POWR-PRO(R) Fuses IDSR Series Indicator(R) POWR-PRO(R) Class RK5 Fuse 600 V AC/DC * Time-Delay * 1/10 - 600 Amperes POWR-PRO(R) Fuses Money is wasted each time a circuit opens and halts production. The indicator window of the IDSR allows maintenance personnel to pinpoint blown fuses immediately. The circuit can then be tested and any problem corrected without unnecessary delay, minimizing costly downtime. Applications DC circuits All general purpose circuits Motors Transformers Solenoids Fluorescent lighting All system components with high in-rush currents Features/Benefits 22 The Littelfuse IDSR Indicator fuse offers a patented solid-state design and provides state-of-the-art reliability along with the convenience of blown fuse indication. The unique design of the IDSR also features a 600 volt AC/DC rating making it ideal for DC applications. * Superior Performance - Littelfuse leading edge metallurgy eliminates all moving parts in a true dual-element design. The IDSR also provides superior time-delay to withstand minor current surges without sacrificing protection for sustained overloads or shortcircuit conditions. * 600 Volt AC/DC Rating - The IDSR is UL Listed for 600 volts AC/DC, which makes it ideal for a variety of applications. It is also MSHA approved. * Reduce Downtime - Costly downtime is minimized using Littelfuse Indicator fuses. A glance at the indicator window tells if the fuse has blown. If the window is dark, the fuse has opened. It's that simple. * Increase Safety - Littelfuse Indicator Fuses minimize exposure to "live" circuit parts while searching for a blown fuse. Other forms of indication require current to power a light. Littelfuse Indicator fuses can be identified with the power off.
