Current-Limiting UL 489 Miniature Circuit

May 12, 2020
Designed and dual-rated for AC and DC applications, the Eaton FAZ-NA and FAZ-NA-L series current-limiting miniature circuit breakers from AutomationDirect offer protection for application with up to 63 amps.

Eaton FAZ-NA and FAZ-NA-L series current-limiting miniature circuit breakers from AutomationDirect offer optimum and efficient protection for feeder, branch, and control circuits up to 63 amps. These DIN-rail mountable circuit breakers are available with B, C, or D trip characteristics in accordance with UL 489.

The new FAZ-NA-L series is rated at 240VAC, the existing FAZ-NA series is rated at 480Y/277VAC. The magnetic trip point of newly added B-curve units is three to five times the rated current and is typically used for resistive loads such as conductors or heaters.

Designed for dual rated AC or DC applications, single-pole, two-pole, and three-pole models are available. The current limiting design provides fast short circuit interruption that reduces damaging let-through energy.

Starting at $14.50, FAZ-NA and FAZ-NA-L series miniature circuit breakers are UL, CSA, and CE listed and have a 1-year warranty.
