63 A switch-disconnector-fuse for UL J fuses
The GS2GU3 is a 3-pole switch-disconnector-fuse from the TeSys GS range, rated 63 A operational current with a 17.6 kA short-circuit withstand. It accepts UL Class J fuses, so the interrupting rating follows the fuse's SCCR — the switch itself is rated for that fault level at 400 V.
Mounting and panel fit
Plate-mount footprint: 5.9 in wide by 5.4 in tall, 4.8 in deep. The external frontal handle operates the 3 NO contacts. Power circuit terminals accept ring lugs on 6–16 mm² wire, torqued to 31.0 lbf·in (3.5 N·m).
Durability and environment
Rated 6,000 electrical cycles and 10,000 mechanical cycles. The body withstands 960 °C glow-wire (fire resistance). Storage range -40 to 176 °F, operation -4 to 158 °F. IP20 with the terminal cover fitted — suitable for enclosed panel use, not washdown.
