Westinghouse FWF3040L - 40A, 415VAC, 3-Pole, Circuit Breaker

Meet the Westinghouse FWF3040L, a robust 40A, 415VAC, 3-pole circuit breaker engineered for demanding electrical environments. This unit is built to deliver reliable overcurrent protection while supporting the needs of modern panelboards, switchboards, and control panels.

Key capabilities designed for real-world use:

• Current rating: 40A, providing precise protection for feeders, sensors, and motor circuits
• Voltage rating: up to 415VAC, ideal for three‑phase distribution in industrial and commercial settings
• Poles: 3-Pole configuration to accommodate true three‑phase systems and MCCs (motor control centers)
• Durable construction to withstand the rigors of distribution panels, control panels, and OEM enclosures
• Simple, reliable protection that helps minimize downtime by preventing fault currents from propagating through critical circuits

Where this breaker shines

• Industrial environments with three‑phase equipment where dependable overcurrent protection is essential
• Commercial facilities housing complex panelboards and switchgear that demand consistent performance
• OEM applications requiring a compact, three‑pole solution for compact control panels and equipment enclosures
• Motor control centers (MCCs) and distribution panels where safe, predictable operation is a priority

Why choose the Westinghouse FWF3040L

Designed to align with the realities of real-world electrical systems, this 3‑pole breaker delivers targeted protection for three‑phase circuits while maintaining a straightforward installation footprint.
