Westinghouse | 1256C10G13 | Circuit Breaker | 300A | 3-Pole | 600V | Bolt-On

Meet the Westinghouse 1256C10G13 circuit breaker — a purpose-built, bolt-on 3-pole protector designed for demanding electrical environments. With a 300A rating and a 600V operating range, this unit is engineered to deliver dependable overcurrent protection in systems that require a precise, high-capacity solution. Its bolt-on mounting simplifies installation and replacement in compatible panels, making it ideal for maintenance, retrofit, and replacement projects where matching specs matters most.

• Amperage: 300A
• Pole configuration: 3-Pole
• Voltage rating: 600V
• Mounting style: Bolt-On
• Best reference for compatibility: Part number 1256C10G13

This breaker is particularly well-suited for scenarios where equipment reliability and fast, straightforward upgrades are needed. Use it when you’re conducting maintenance on existing panels, retrofitting to accommodate higher load demands, or replacing worn-out components with a unit that preserves the panel’s intended protection characteristics. The explicit part number 1256C10G13 serves as the most reliable signal for compatibility, reducing guesswork and ensuring you’re selecting the correct unit for your setup.

Why choose this Westinghouse 1256C10G13

Clear alignment with established panel configurations means fewer surprises during installation. The three-pole design ensures balanced protection across all live conductors in 600V circuits, while the bolt-on mounting provides a secure, vibration-resistant attachment that holds up under demanding environments. This combination helps maintain electrical safety, protects downstream equipment, and supports consistent trip performance in line with your system’s protection strategy.

Ideal use cases

Best for industrial and commercial applications where panels are designed for bolt-on protection and require a reliable 300A, 600V solution. Suitable for:

• Maintenance projects that refresh aging protection components
• Retrofits that upgrade system capacity without reconfiguring existing buswork
• Replacements that demand exact spec matching to maintain electrical protection and panel coordination

Before placing an order, double-check that your panel is compatible with the 1256C10G13 specification by using the part number as the primary reference. This ensures a smooth installation, preserves protective coordination, and minimizes downtime on critical electrical infrastructure.
