Schneider Electric GS1DU3 General Purpose Switch

Schneider Electric GS1DU3 TeSys GS three‑pole switch‑disconnector fuse provides combined protection and isolation for power circuits in industrial panels. Rated for 600 V and designed to accept UL Class J fuse links, it carries a conventional free‑air thermal current Ith of 30 A and is intended for use with Class J fuse links (fuse size J). The unit features an external front‑side operating handle and is lockable with a door interlock to ensure safe maintenance, with robust, compact handles typical of the TeSys GS family. It delivers high short‑circuit performance up to 100 kA, enabling reliable protection in demanding installations. This GS1DU3 is commonly used to protect motors and feeders in control panels and can support motor applications up to 15 kW at 400 V AC‑23, making it a practical, integrated solution that simplifies panel design while preserving clear isolation points for servicing.
