FAQs
Install the XT1 125 A MCCB in a compatible panel using front terminals designed for bolt connections. Use a mains screwdriver to tighten the main circuit screws to 6 N·m, and connect busbars within 45.5 to 80 mm². Ensure correct alignment, verify wiring diagrams, and close the enclosure to complete a secure, serviceable installation.
For UL489, the XT1 3P 125 A device provides 100 kA interrupting rating at 240 V AC, 65 kA at 480 V AC, and 25 kA at 600Y/347 V AC, with DC ratings of 2 poles in series at 250 V DC and 4 poles in series at 500 V DC. These ratings support rapid fault interruption across typical industrial feeders.
Yes. The device carries RoHS declarations and REACH compliance, plus an Environmental Product Declaration (EPD) and design for recycling aligned with EN45555. It is positioned for industries needing regulatory certainty and lower environmental impact while maintaining performance in power distribution and control panels.
