Eaton NZMH2-AF30-BT-NA NZMH2 MCCB - UL Listed
Part Number: NZMH2-AF30-BT-NA
Quick Summary
NZMH2-AF30-BT-NA is a complete molded case circuit breaker that protects electrical distribution panels in industrial facilities. Designers often grapple with coordinating thermal overload protection with fast magnetic trips while keeping dense panel layouts manageable. UL Listed certification supports safety and reliability for demanding environments, and the NZM2 frame enables compact, modular installations across standard switchgear. This model combines adjustable thermal protection with fixed magnetic trip and a three-pole design to deliver precise circuit protection without unnecessary nuisance tripping. In addition, its front-frame clamp connections and available rocker lever and motor-drive accessories streamline installation and maintenance, delivering lower lifecycle costs and higher panel uptime.

FAQs
NZMH2-AF30-BT-NA uses the NZM2 frame and front frame clamp terminals, making it compatible with standard distribution panels, motor control centers, and panel boards that accept three-pole MCCBs. The compact 4.13 in x 4.05 in x 7.24 in footprint supports efficient panel layouts without sacrificing protection.
The device is a 3-pole MCCB rated at 30 A, with a voltage rating of 690 Vac / 750 Vdc. It features adjustable thermal overload protection and fixed magnetic trip, a short-circuit breaking capacity of 150 kAIC and an interrupt rating of 85–150 kAIC, suitable for robust distribution circuits in industrial settings.
Yes. With a three-pole NZM2 frame, adjustable thermal trip, and motor-drive accessory compatibility, it is well suited for motor control centers and panels where controlled startup/shutoff and reliable protection are critical for uptime and equipment longevity.
The product is UL Listed, providing recognized safety and performance compliance for industrial electrical protections. This certification supports installation in governed electrical panels and aligns with standard safety expectations across many regions.
Plan for routine inspections of trip settings, verify front-frame connections remain tight, and monitor accessory components like rocker levers or motor-drive options for wear. The 1-year warranty (or 18 months from shipment) offers protection during initial deployment, while UL Listing supports ongoing reliability in demanding environments.
