Moeller FAZ-D40/3 - 40A, 240VAC, 3-Pole, Miniature Circuit Breaker (MCB)

Meet the Moeller FAZ-D40/3 — a 40A, 240VAC, 3-Pole Miniature Circuit Breaker (MCB) designed to deliver dependable overcurrent protection where it matters most. Built for panelboards, switchboards, and control panels, this unit excels in industrial, commercial, and OEM environments that demand safe operation and minimized downtime.

• Three-pole protection for true three-phase circuit interruption, helping prevent phase imbalances and protecting connected equipment.
• 40A, 240VAC rating aligns with common industrial feeders and loads, providing robust protection without over- or under-sizing.
• Versatile application ideal for panelboards, switchboards, and control panels in a range of settings—from manufacturing floors to commercial electrical rooms.
• Dependable overcurrent protection quickly isolates faults to keep systems safe and reduce the impact of outages on production and operation.
• OEM-friendly design suited for original equipment manufacturing and retrofit projects that require reliable, straightforward protection.

Practical use cases

• Guard three-phase motors and feeders in distribution panels and motor control centers to ensure controlled, safe startup and shutdown.
• Equip control panels and switchgear in commercial facilities with predictable fault isolation and enhanced safety.
• In OEM applications, integrate a trusted Moeller breaker that pairs with standard three-phase electrical architectures.

Why this choice stands out

The FAZ-D40/3 delivers a precise balance of performance and practicality for three-phase systems. With a clear 40A current rating at 240VAC and a 3-Pole configuration, it provides reliable protection for essential equipment while simplifying installation in distribution panels and control centers. It’s the kind of component maintenance teams rely on to maintain uptime and safety across everyday industrial operations.

Tips for best results

• Verify your load and conductor ratings align with the 40A, 240VAC specification to avoid nuisance trips.
• Use as either main feeder protection or targeted branch protection within panelboards and motor control centers to quickly isolate fault conditions.
