Meet the Westinghouse HFD2040BP10 circuit breaker—a purpose-built solution for protecting 277-volt electrical distributions in commercial and industrial settings. This 40-amp, 2-pole breaker is designed for bolt-on mounting, delivering a secure, durable connection that stands up to the demands of real-world installations.

Key specifications at a glance

• Amperage: 40A
• Poles: 2-Pole
• Voltage: 277V
• Mounting: Bolt-On
• Part reference: HFD2040BP10

This combination makes it well-suited for two-leg protection of 277V circuits such as lighting, motors, and other commercial loads where reliable overcurrent protection is essential. The bolt-on design provides a solid, vibration-resistant connection in compatible panels, enabling straightforward field replacement or retrofit without complex wiring changes.

Why choose this Westinghouse model

• Precise compatibility for 277V systems: Specifically rated to interrupt and protect two hot legs in 277V circuits, aligning with many commercial panel boards and distribution setups.
• Targeted replacement for bolt-on panels: Ideal for maintenance or retrofit projects where a like-for-like upgrade keeps existing panel configurations intact.
• Part-number accuracy matters: The HFD2040BP10 designation serves as the most reliable reference for compatibility, so cross-check with your panel’s requirements before ordering.

What to consider before you purchase

Confirm fit and ratings before ordering to ensure seamless integration with your panel. Use the part number HFD2040BP10 as the primary reference to match the breaker to your system’s bolt-on 2-pole, 277V specification. This helps you avoid mismatches and minimizes downtime during replacement or retrofit projects.

Practical tips and installation notes

• Power down the panel and verify there are no indications of live circuits before handling the breaker.
• Ensure the panel is designed to accept bolt-on breakers of this frame and voltage rating.
• Follow the panel manufacturer’s torque and mounting guidelines for a secure installation.
• Keep this unit on hand for quick replacement when a 2-pole, 277V protection is required for two hot legs.
