The Shawmut TR400R fuse is a 400 Amp, 250 VAC protection device designed to interrupt excessive current in electrical circuits. Rated for 400 A at 250 V AC, it provides overcurrent protection for systems operating at those voltages and helps safeguard wiring and connected equipment from fault conditions. As a Shawmut component, the TR400R is intended for high-current protection scenarios where a 250 VAC supply is present, delivering reliable interruption when the current exceeds the fuse’s rating.
