Eaton / Cutler-Hammer FAZ-B32/3-NA Miniature Circuit Breaker

The B-curve magnetic trip point is calibrated to trip between 3 and 5 times the rated current. This profile is designed for applications with low inrush currents, such as resistive loads, lighting, and control circuits.

Yes, the -NA suffix indicates this miniature circuit breaker is UL 489 listed for branch circuit protection. This allows it to be used for feeder and branch circuits, unlike UL 1077 supplementary protectors.

Yes, this breaker is dual-rated for both AC and DC applications, making it suitable for control panels requiring DC branch protection up to 96VDC.

The breaker mounts on a standard 35mm DIN rail and has a module width of 17.5mm per pole. This 3-pole unit requires a total of 52.5mm of rail space.

Yes, the FAZ-NA series supports field-installable accessories. Auxiliary contacts, bell alarms, and shunt trips can be retrofitted to the side of the breaker to enhance diagnostic and control capabilities.

Yes, the FAZ-NA series features reverse feed capabilities. Power can be supplied from either the line or load side terminals without affecting the breaker performance.

Yes, it includes a color-coded contact position indicator on the front face. Green indicates the contacts are open and isolated, while red indicates the contacts are closed.

Yes, it is a current-limiting breaker. It is designed to interrupt fault currents within one-half cycle, which reduces peak let-through energy and helps protect downstream wiring and equipment from damage.

This model features standard box lug terminals with captive screws to prevent hardware loss during installation. If your application requires ring-tongue terminals, you would need the FAZ-RT series instead.
