Westhinghouse FB3040P - 40A, 3040-Pole, Circuit Breaker

The Westhinghouse FB3040P is a capable 40A circuit breaker engineered for serious electrical protection in demanding environments. With a flexible 3040-Pole configuration, it’s built to slot into panelboards, switchboards, and control panels where multi-circuit protection is needed without crowding the enclosure.

• 3040-Pole configuration for flexible installations — protect multiple circuits with a single device, enabling streamlined wiring and simplified panel layouts.
• 40A current rating — precisely sized protection for feeders, motor circuits, and critical power paths in industrial, commercial, and OEM equipment.
• Robust overcurrent protection — designed for safe operation and reliable interruption of fault conditions, helping to minimize downtime and equipment damage.
• OEM-friendly and panel-ready — engineered to integrate smoothly into standard distribution panels and motor control centers, reducing installation time and complexity.
• Versatile application across systems — ideal for panelboards, switchboards, and control panels in manufacturing lines, HVAC controls, and automated machinery.

Use cases and scenarios

• Industrial environments where a single protective device must guard multiple motor circuits across a control panel.
• Commercial distribution panels requiring dependable 40A protection for critical feeders and branch circuits.
• OEM equipment designs that need compact, multi-pole protection to simplify wiring and improve reliability in control architectures.

Why this breaks away from generic options — The FB3040P’s 3040-Pole design delivers multi-circuit protection in a compact form, reducing the number of separate breakers you need and simplifying wire routing. This translates to faster installation, easier future upgrades, and a cleaner, safer panel environment.

Installation and care tips

• Confirm the enclosure and mounting method support a 3040-Pole arrangement and follow all relevant electrical codes during installation.
• Wire conductors according to the system layout and ensure appropriate conductor sizing for the 40A rating.
• Periodically inspect connections and ensure the breaker remains securely seated in the panelboard, switchboard, or control panel.

Designed for industrial, commercial, and OEM applications where dependable protection and safe operation are critical, the Westhinghouse FB3040P delivers targeted 40A protection with versatile, multi-circuit capability. It’s a practical choice for engineers and technicians looking to optimize panel space, simplify wiring, and keep critical equipment protected.
