TDK Corporation introduced the MT40 series ThermoFuse varistors, compact surge protection components capable of handling peak surge currents up to 50 kA.
The new devices combine a compact form factor with integrated thermal disconnect technology and patented overmolding, enhancing safety and reliability in high-voltage environments. The MT40 series supports AC voltages from 150 V to 550 V and DC voltages from 200 V to 750 V, with a short-circuit current rating of up to 200 kA.
These components are designed for applications including photovoltaic systems, industrial power supplies, outdoor lighting, telecommunications equipment and surge protection devices. Additional features such as a micro-switch for remote monitoring and optional visual indicators improve system integration and operational safety.
