Westinghouse | FDC3045V | Circuit Breaker | 45A | 3-Pole

The Westinghouse FDC3045V is a dependable 3-pole circuit breaker rated at 45 amps, designed to safeguard your electrical panel from overloads while supporting maintenance, retrofit, and replacement projects. Built by Westinghouse, this unit is tailored for compatibility with systems that specify the FDC3045V part number as the reference point for a secure fit.

Key specifications and what they mean

• Amperage: 45 A – provides robust protection for circuits that demand reliable interrupting capacity while minimizing nuisance trips for normal loads.
• Poles: 3-Pole – suitable for three-phase configurations or multiple branch circuits in a single device, delivering coordinated protection across connected feeders.
• Part number: FDC3045V – use this as your primary compatibility reference when cross-checking with existing panels or replacement guides.

Why this Westinghouse breaker stands out

Unlike generic substitutes, this FDC3045V unit comes from Westinghouse’s dependable line of circuit protection products. The three-pole design creates consistent switching behavior across phases, helping reduce contact wear and ensuring stable performance in demanding environments. It’s an ideal choice for technicians performing panel maintenance, upgrading older installations, or stocking spare parts for quick field replacements.

Who needs the FDC3045V?

This breaker is best for professionals and experienced DIYers working on Westinghouse panel boards that call for a 3-pole, 45-amp device. It’s particularly useful in commercial spaces with three-phase circuits or multi-branch setups where a single protective device must manage multiple conductors safely.

Practical use cases

• Maintenance and service calls where a precise, drop-in replacement is required to minimize downtime.
• Retrofit projects that upgrade older equipment to a modern, safer protection strategy.
• Replacement for a failed or tripped breaker in panels that spec 3-pole, 45A protection using the FDC3045V reference.

Installation and safety notes

Install only after power is fully shut off and systems are de-energized. Verify ratings and panel compatibility using the FDC3045V part number before ordering. If you’re unsure about fit, consult the panel documentation or a licensed electrician to ensure a correct, code-compliant installation.
