FA36040 - 40 Amp Circuit Breaker

FA36040 - 40 Amp Circuit Breaker

Whether you’re safeguarding commercial HVAC systems or industrial electrical circuits, the FA36040 circuit breaker delivers reliable protection with premium build quality. This 40-amp, three-pole I-Line breaker uses thermal-magnetic trip technology to respond quickly to overloads and short-circuit faults, helping to maintain uptime while protecting your equipment and wiring. Built for demanding environments, it brings high interruption ratings and certified compliance, so you can install with confidence.

Key Features and Benefits

• Thermal-Magnetic Trip Unit: Combines a thermal element for overload protection and a magnetic element for fast short-circuit response, reducing the risk of damage or downtime.
• Durable Construction: Designed with high-quality materials and rugged components to perform reliably even under harsh industrial or commercial conditions.
• High Interrupting Capacity (AIC): With an 18 kA interrupting rating at 480 VAC and 25 kA at 240 VAC, this unit is capable of handling significant fault currents and protecting your system when events occur.
• 3-Pole I-Line Format: Simplifies installation in panelboards designed for I-Line breakers and supports three-phase loads in one device.
