The MS32 20008 inrush current limiting thermistor from Ametherm offers a maximum steady state current of 8A (up to +25°C), resistance of 20Ω ±25% (at 25°C) and a maximum recommended energy rating of 250J. Ametherm’s MegaSurge™ series of inrush current limiting NTC thermistors reduce costs and greatly simplify designs. In addition, they increase safety by eliminating the fire hazard associated with failed relays. While traditional thermistors are only certified for input voltages from 85 VAC to 265 VAC, UL recognised MegaSurge™ devices are certified for single and three phase input voltages up to 480 VAC. These specifications are the highest of any single-solution inrush current limiting device on the market.
