Warystory ThermoFuse MT40

TDK MT40 ThermoFuse Varistors provide robust protection up to 50kA while minimizing size (38.0mm length x 15.2mm width x 40.9mm height). The MT40 series is commonly used in inverters, industrial power supplies, outdoor lighting, telecommunications systems, and surge protection devices (SPDs). These TDK ThermoFuse varistors are designed for extreme electrical conditions and have a peak surge current capability of up to 50kA (8/20μs pulse) and a short-circuit current rating of up to 200kA. The series is recognized as a UL 1449 Type 1CA component assembly, designed for applications with voltages ranging from 150V_AC to 550V_AC and 200V_DC to 750V_DC.
