FCL34045 - 45 Amp Circuit Breaker

FCL34045 - 45 Amp Circuit Breaker

Upgrade the electrical protection in your commercial or industrial setup with the FCL34045 45 A circuit breaker. This three-pole, 45-amp device is built to guard your system against both overloads and short circuits with a thermal-magnetic trip mechanism, offering reliable performance where it matters most. With an impressive interrupting capacity of 65 kA at 480 VAC and 100 kA at 240 VAC, the FCL34045 gives you high-end protection under demanding conditions. Its molded-case design provides long-lasting durability in a compact form, making it a superb fit whether you’re installing in panelboards, switchboards or motor-control centres. Rated for 60 Hz and ambient environments up to 40 °C, it adapts to a broad spectrum of applications and stands up to challenging industrial conditions.

Key Features & Benefits

• High fault-clearing capacity: With interrupting ratings of 65 kA @ 480 VAC and 100 kA @ 240 VAC, this breaker is ready for heavy fault currents in high-demand settings.
• Thermal-magnetic trip operation: Combines overload (thermal) and short-circuit (magnetic) protection in one unit, so you get both forms of safety in a single device.
• Durable, compact construction: The molded-case body is built to last, and the space-saving footprint helps when installations are tight.
• Flexible placement: Works well in panelboards, motor control centres (MCCs), switchboards, and industrial enclosures—ideal for installations in commercial and industrial environments.
• Reliable under real-world conditions: Rated for standard 60 Hz supply and ambient temperatures up to 40 °C, so it’s built to perform even in less-than-ideal environments.
