FAQs
Begin with de-energizing the panel, mount the unit in a suitable rack space, and ensure the 32.5 to 100 mm² busbars align with the front terminals. Connect conductors using M6 screws, tightening to 6 N·m, and verify correct pole sequencing. Check insulation clearances and re-energize in accordance with UL489 guidelines after a functional test.
Key ratings include rated operational voltage of 600 V AC / 500 V DC, rated uninterrupted current (Iu) of 125 A, and four poles (4P). Opening time is about 30 ms. Interrupting ratings per UL489 cover various voltages, with 150 kA at 240 V AC, 65 kA at 480 V AC, and 65 kA at higher DC configurations in series arrangements.
Yes. The XT2 subtype and four-pole front-terminal design align with Tmax XT-based controls, offering reliable isolation and straightforward wiring in motor control centers and machine control panels.
