Thermistors Withstand 80A Inrush

Ametherm inrush current limiting NTC thermistors designed to withstand high input energy of 1200J and steady-state currents from 50A to 80A at 680 V. Offered in DIN-rail-mountable packages, MM35-DIN series devices are optimized for power distribution in high-power industrial and green energy applications including variable-frequency motor drives, transformers, wind turbines, large inverters, and single- and three-phase motors.

 

The MM35-DIN series consists of four thermistors featuring resistance at 25 °C from 0.2 Ω to 1.5 Ω, maximum power of 38.4 W, and thermal time constants of less than 300 s. The devices feature diameters of 68.0 mm with thickness of 8.5 mm and 9.5 mm.

The space- and cost-saving thermistors provide simple one-component alternatives to using power resistors with relays or MOSFETs, greatly simplifying designs. For easy installation, the devices are designed for use with a DIN block. This allows for mounting within a power control box using only a screwdriver. Pricing for U.S. delivery starts at $47.90 each.
