FAQs
NZMN2-AF70-BT-NA uses front-frame clamp terminals on the NZM2 frame, enabling quick, secure mounting in distribution panels. When planning installation, ensure clearance for a three-pole device and verify that the box terminals accommodate the conductor sizes typical for 70A feeders. This minimizes wiring errors and speeds up commissioning while maintaining compliant protection.
The device is rated for 70A with a short-circuit capacity of 50 kAIC and voltage ratings of 690 Vac / 750 Vdc. This combination supports robust short-circuit protection for medium-power distribution circuits, enabling rapid fault isolation in industrial panels and reducing the risk of equipment damage during transient faults.
Yes. With three poles, a 70A rating, and a 50 kAIC interrupt capacity, this MCCB is designed for distribution circuit protection in industrial panels and motor control centers. Its NZM2 frame and compatible front-frame clamp mounting streamline integration, wiring, and maintenance in space-constrained enclosures.
The NZMN2-AF70-BT-NA carries UL Listed certification. For broader regulatory compliance, consult Eaton for confirmation of additional certifications such as CE or SIL. This ensures alignment with regional safety standards and helps meet project-specific approval requirements during audits and commissioning.
Maintenance is straightforward due to standardized box terminals and front-frame mounting that simplify inspections and replacements. The 70A rating and 50 kAIC capacity reduce downtime during fault events, while UL-listed certification supports compliance and procurement efficiency, contributing to a favorable total cost of ownership over the panel life.
