Westinghouse | NB31000 | Circuit Breaker | 1000A | 3-Pole | 600V | Bolt-On

Meet the Westinghouse NB31000 circuit breaker — a robust, bolt-on solution crafted for demanding electrical installations. With a 1000A rating and 600V capacity across a 3-pole design, this breaker is built to safeguard large feeders and three‑phase equipment in industrial, commercial, and retrofit environments. Designed for maintenance, retrofit, and replacement projects, it delivers reliable performance when you need it most.

• 1000A amperage— top-tier protection for main feeders and heavy-load circuits that demand strong fault isolation.
• 3-Pole design— ideal for standard three-phase systems, ensuring coordinated protection across all phases.
• 600V maximum voltage— suitable for a wide range of industrial and commercial power setups; verify panel compatibility.
• Bolt-On mounting— secure, durable installation that simplifies retrofits and reduces field assembly time.
• Clear compatibility reference— part number NB31000 is your best guide for fit; always confirm fit and ratings before ordering.

Why this matters in real-world applications: the NB31000 provides a straightforward, dependable replacement option in panels designed for Westinghouse bolt-on breakers. The bolt-on approach ensures a solid mechanical connection and clean electrical contact, which translates to more reliable protection during peak loads and switching events. This is particularly valuable in environments where downtime is costly and rapid, accurate replacements are essential.

Ideal use cases include:

• Retrofits in aging or expanded facilities where a high-capacity, three-phase breaker is required to protect large feeders.
• Maintenance or replacement in industrial control panels that specify Westinghouse NB31000-style bolt-on breakers.
• Upgrades to support heavier electrical loads in commercial spaces or light manufacturing lines that run on 3-phase power.

Practical guidance for selection and installation:

• Always verify that your panel is designed to accept bolt-on, 3‑pole NB31000 devices and that the ambient and wiring configurations align with the 1000A, 600V rating.
• Use the NB31000 part number as the primary reference when sourcing a replacement to ensure mechanical fit and electrical compatibility.
• Prepare for installation by ensuring secure bus connections and following the panel manufacturer’s torque specifications to maintain performance and safety.

For professionals prioritizing reliability, compatibility, and efficient retrofits, the Westinghouse NB31000 circuit breaker is a precise, purpose-built choice. It’s the right fit when you need a high-capacity, three-pole, bolt-on solution that aligns with established Westinghouse panels and systems.
