Eaton FAZ-C40/3-NA Miniature Circuit Breaker 40A 3P

Product Description

The EATON FAZ-C40/3-NA is a miniature circuit breaker (MCB) designed for overcurrent and short-circuit protection in industrial and commercial electrical distribution systems. Rated at 40 amps with a 3-pole configuration, this breaker is suited for three-phase branch circuit protection where reliable, compact protection devices are required. The C-curve trip characteristic makes it appropriate for resistive and moderate inductive loads. Licensed electricians and electrical contractors install this device in panelboards, motor control centers, and distribution enclosures.

The FAZ-C40/3-NA is used in commercial and light industrial applications where three-phase branch circuit protection is needed. It fits DIN rail-mounted enclosures and panelboard assemblies common in industrial control panels, machinery, and building electrical systems. The C-curve trip characteristic suits loads such as lighting, heating, and general-purpose motors with moderate inrush currents.

Key Features

• 3-pole design provides three-phase overcurrent and short-circuit protection in a single device
• C-curve trip characteristic rated for moderate inductive and resistive load applications
• 40-amp continuous current rating for branch circuit protection
• Compact miniature circuit breaker form factor for DIN rail mounting
• North American (NA) version compliant with applicable UL and CSA standards for the North American market

Compatibility

Designed as an OEM-style replacement or direct installation miniature circuit breaker for DIN rail-mounted panelboards and industrial control enclosures requiring a 3-pole, 40-amp, C-curve device in North American-compliant configurations.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panel or enclosure before installing or replacing any circuit breaker. Verify that the DIN rail mounting track is properly sized and secured before snapping the breaker into place. Do not exceed the breaker's marked current rating when sizing connected loads.
