Westinghouse | 1256C10G05 | Circuit Breaker | 400A | 2-Pole | 600V | Bolt-On

Meet the Westinghouse 1256C10G05 circuit breaker — a robust 400A, 2-pole, 600V bolt-on protection device designed for demanding panels and retrofit projects that demand exacting compatibility.

Key specs at a glance

• Amperage: 400A
• Poles: 2-Pole
• Voltage: 600V
• Mounting: Bolt-On

Why this Westinghouse breaker stands out

• Exact compatibility with the part number 1256C10G05 — use this reference to ensure a seamless fit in your panel. The manufacturer notes that the part number is the best reference for compatibility, so confirm fit and ratings before ordering.
• Secure bolt-on mounting provides a solid mechanical connection, reducing vibration and ensuring reliable protection in the demanding environments common to commercial and industrial spaces.
• Maintenance, retrofit, and replacement ready — swap in quickly when upgrading or replacing aging equipment without overhauling the entire distribution setup.
• 600-volt operation tailored for medium-voltage distribution panels and industrial control circuits where higher voltage is standard.

Use cases and scenarios

• Replacing a failed breaker in an existing 600V, heavy-duty panel that requires a 400A, 2-pole bolt-on design.
• Retrofits in aging electrical systems where upgrading to a higher amp or different mounting style is not feasible — sourcing this exact part maintains panel integrity and safety compliance.
• New installations in industrial settings that require a bolt-on connection for a durable, vibration-resistant protection solution.

Practical considerations for installation

• Before ordering, verify that your panel accepts bolt-on breakers and that 400A at 600V aligns with your feeder and bus configuration.
• Because you’ll be aligning with a specific part number, use 1256C10G05 as the primary reference to confirm compatibility across components and documentation.
• Follow all safety standards and manufacturer instructions during installation to ensure proper clearance, torque (as specified in your panel manual), and secure wiring terminals.
