FAQs

For installation, use the front frame clamp terminals to secure wiring and ensure proper alignment with the NZM2 frame. Verify panel space for a three-pole device and position the breaker to allow accessibility for manual operation and routine testing. Confirm torque per manufacturer recommendations during assembly and ensure routing minimizes heat buildup and vibration in the enclosure.
The device offers adjustable thermal and magnetic trip settings to tailor overcurrent protection to specific loads. By coordinating with feeder protections and motor starting currents, the breaker reduces nuisance trips and improves selective clearance. This is particularly beneficial in mixed-load panels where motors, drives, and resistive loads share the same distribution circuit.
Yes. The NZMH2-A80-BT-NA is rated for 690 Vac and 750 Vdc, providing three-pole protection with a robust interrupt capacity. The front-frame clamp terminals and NZM2 frame support reliable mounting in compact panels, making it suitable for mixed high-voltage AC and DC distribution arrangements in industrial settings.
The product carries UL Listed certification, affirming compliance with essential safety standards for electrical protection devices. While the data specifies UL Listed status, always verify regional regulatory requirements with the manufacturer, as additional certifications or markings may be needed to meet local codes and customer procurement policies.
The NZMH2-A80-BT-NA combines rugged protection with adjustable trip settings, enabling precise coordination and reducing downtime due to nuisance tripping. Its 85–150 kAIC interrupt capacity and front-frame mounting simplify maintenance and replacement, while the 1-year warranty (18 months from shipment) provides early-life support, supporting lower lifecycle costs and predictable maintenance budgeting.
