FAQs
The NZMH2-AF15-BT-NA uses the NZM2 frame with front-frame clamp for straightforward installation in compatible distribution panels. Its three-pole configuration aligns with common MCC and control panel architectures, simplifying retrofits and new builds. Ensure panel enclosures support NZM2 mounting dimensions and that wiring terminals are prepared for 690 Vac/750 Vdc ratings.
This device combines adjustable thermal protection with a fixed magnetic trip. That means overload conditions are coordinated to avoid nuisance trips, while short-circuit faults trigger rapid disconnection. The result is improved selectivity, quicker fault isolation, and safer downstream equipment in industrial automation and heavy-duty circuits.
Yes. With a 15 A rating, 690 Vac / 750 Vdc capability, and three-pole design, the NZMH2-AF15-BT-NA is well-suited for motor control centers and distribution panels in industrial settings. Its high short-circuit current rating (up to 150 kAIC) supports reliable protection for drives and feeders operating in demanding environments.
The NZMH2-AF15-BT-NA carries UL Listed certification, providing recognized safety and performance validation for North American installations. This supports compliance documentation and audit readiness when integrating into standard electrical protections in industrial facilities.
The combination of front-frame mounting, compatible NZM2 frame, and accessible accessories (rocker lever, motor drive) simplifies maintenance, reduces commissioning time, and minimizes downtime. The device’s robust protection reduces fault-related wear on feeders and motors, contributing to lower maintenance costs and improved uptime over the lifecycle of the installation.
