Westinghouse | EHB1100 | Circuit Breaker | 100A | 1-Pole | 277V

Meet the Westinghouse EHB1100 Circuit Breaker—a focused, reliable solution for protecting 277V circuits with clarity and confidence. This 100A, 1-Pole device is crafted for maintenance, retrofit, and replacement projects where exact specifications matter, delivering dependable overcurrent protection when you need it most.

Key specifications at a glance:

• Amperage: 100 A
• Poles: 1-Pole
• Voltage: 277 V
• Part number: EHB1100

Why this matters in real-world setups: 277V circuits are common in commercial environments—lighting systems, fans, and certain feeders—and require a precisely matched breaker to ensure proper protection and predictable trip behavior. The EHB1100 is designed to fit these applications without guesswork, helping you maintain safe, compliant electrical protection for your 277V infrastructure.

Ideal use cases:

• Maintenance and service on panels that rely on 1-Pole breakers rated for 277V
• Retrofit projects where upgrading to 100A protection on a 277V circuit is appropriate
• Replacement of a failed unit in facilities that standardize on a 1-Pole, 277V configuration

How to ensure a perfect fit:

• Verify that your panel accepts 1-Pole, 277V breakers and that the circuit you’re protecting aligns with a 100A rating
• Use the part number EHB1100 as the primary reference to confirm compatibility with your panel model
• Before ordering, double-check the panel labeling and documentation to avoid mismatches and unnecessary returns

Practical value in everyday electrical work: choosing the Westinghouse EHB1100 means sticking with a trusted, straightforward solution for 277V, 100A, single-pole protection. It minimizes guesswork, aligns with common panel architectures, and supports smooth maintenance or upgrades in commercial and industrial environments.
