FA36040 **Old Style** 40 Amp Circuit Breaker

FA36040 **Old Style** 40 Amp Circuit Breaker

Discover the FA36040 40A Circuit Breaker — a high-performance protection device built to deliver reliable overcurrent defense in demanding industrial and commercial electrical systems. Designed for a 600V line-voltage environment and carrying a 40 A rated current across three poles, this breaker features a thermal-magnetic trip unit that reacts both rapidly to magnetic faults and steadily to thermal overloads. Its compact footprint and I-Line mounting mode make it straightforward to install in tight panel environments while delivering consistent protection for motors, lighting banks, HVAC systems and other high-demand circuits. Because it’s engineered to safeguard your assets rather than simply meet code, the FA36040 gives you peace of mind about continuity, safety and system longevity.

Key Features and Benefits

• High voltage and current capability: Supports up to 600 V with a 40 A line rating — suited for heavy-duty circuits.
• Thermal-magnetic trip unit: Combines both thermal and magnetic protection to identify both sustained overloads and instant short-circuit conditions.
• Space-saving design: Compact dimensions allow the breaker to fit into existing panel layouts without significant rearrangement.
• I-Line mounting mode: Quick installation into standard I-Line bus systems, simplifying the fit-in and reducing labor.
• Precise fault response: With magnetic hold current of 400 A and magnetic trip current of 850 A, the unit is tuned for reliable interruption of fault currents while avoiding nuisance trips.
