FAQs
Installation requires mounting the E2NM3600WU18 as a three-pole, N-frame device rated for 600 A. Verify the voltage rating of 1000Y/577 Vac and 250 Vdc, and ensure the undervoltage release is configured at 110-127 Vac rear with a left pigtail. Use proper mounting hardware and confirm wiring compatible with customer terminals, as this unit ships without terminals.
Key specs include 600 A amperage rating, 25 kAIC interrupt rating at 1000 Vac, and 1000Y/577 Vac plus 250 Vdc voltage ratings. It is a three-pole, N-frame, mining-rated molded case circuit breaker with electronic LI trip (Digitrip 310+ compatibility) and undervoltage release 110-127 Vac rear with left pigtail.
Yes. The device is specifically marketed as a mining MCCB with a rugged N-frame, three-pole configuration, and 25 kAIC interrupt capability to handle high fault currents typical in underground mining. Its electronic trip and MSHA-guidance documentation support safer operation and reliable fault isolation in harsh underground conditions.
