It accepts Class J fuses, making it a UL-listed (UL98, CSA C22.2 No 4) disconnecting means for motor branch circuits or feeder disconnects in industrial control panels. The 200 A conventional free-air thermal current (Ith) at 40 °C matches the rated operational current (Ie), so no derating is needed at typical panel ambient temperatures. The 1600 A breaking capacity at 400 V covers most downstream fault scenarios without upstream coordination changes. ## Power Ratings and Interruption Capacity Rated operational power reaches 100 kW at 400 V, 140 kW at 500 V, and 185 kW at 690 V AC — covering motor loads from 130 HP up to 250 HP depending on the supply voltage. The 8 kV rated impulse withstand voltage (Uimp) and 750 V rated insulation voltage (Ui) confirm it handles industrial distribution transients without flashover. Short-circuit making capacity (Icm) is 2 kA at 400 V, and the fuse size J holder limits let-through energy to the downstream conductors. The 6000-cycle electrical durability and 10,000-cycle mechanical durability suit daily switching in production lines, not just infrequent isolation. ## Mounting and Wiring in the Panel Mounts on a plate (not DIN rail) — the 7.7-inch square footprint (196 mm wide × 195 mm tall) and 5.1-inch depth (130 mm) fit standard enclosure backpanels. Power-circuit lugs accept ring terminals from 16 mm² to 152 mm² (0.02–0.2 in²), with a tightening torque of 8.5 N·m (75.2 lbf·in). IP20 protection with the terminal cover installed — finger-safe for the panel interior but not rated for washdown. The external frontal operating handle allows padlocking in the OFF position for lockout/tagout compliance.","metaTitle":"Schneider TeSys GS2MU3 Switch-Disconnector-Fuse, 200 A, UL","metaDescription":"Schneider TeSys GS2MU3 switch-disconnector-fuse, 3-pole, UL 200 A, fuse size J.
