Industrial KU4100UL98

KU4100UL98 is a four-pole UL98 motor disconnect switch from Altech’s UL98 Open/Extended family, designed to sit adjacent to industrial motors to safely isolate power in a non‑enclosed, extended (Extended) format. It is rated for 100 A at up to 600 VAC, with 8–1/0 AWG copper terminals and a short-circuit withstand rating of 50 kA at 600 V, and it provides a lockable OFF position for reliable personnel protection. HP ratings across common voltages include 5 HP (1P, 120 VAC), 10 HP (1P, 240 VAC), 25 HP (3P, 240 VAC), 50 HP (3P, 480 VAC), and 75 HP (3P, 600 VAC), aligning with open‑type motor disconnect usage in demanding environments. UL98 Approval confirms compliance for motor-disconnect applications, and the open/ext style is suitable for installations where the switch is mounted near the motor rather than inside a separate enclosure; typical applications span general motor control in manufacturing, mining, and process facilities.
