Thermodisc G7 MICROTEMP Thermal Cut Off Fuse 5A 144°C

The Thermodisc G7 MICROTEMP Thermal Cut Off Fuse is a compact, global-standard component designed for precise and reliable upper-limit temperature protection. It provides a critical safety function by automatically interrupting an electrical circuit when operating temperatures exceed its rated 144°C threshold, effectively guarding against overheating.

Part of the MICROTEMP series, this fuse offers an accurate, one-shot operation that permanently cuts electrical power upon activation. Its miniature design, approximately two-thirds the size of older G4 and G5 series fuses, makes it ideal for modern applications where space for components is at a premium. The low-resistance construction ensures efficient performance without compromising safety.

This thermal fuse is highly versatile and capable of meeting the rigorous safety requirements of various applications, including transformers, motors, battery packs, and consumer electronic circuits. It is available with multiple termination options—cut, formed, or terminated leads—as well as mounted and potted variants for different installation needs.

The product holds approvals from major international safety organisations, including UL/CSA, VDE, CCC, METI, and BEAB, underscoring its reliability for global use. With a current interrupt capacity of up to 5A at 250V AC, it provides robust protection for a wide range of electrical devices in industrial, safety-critical, portable, and consumer electronics settings.
