Westinghouse | EHB1015 | Circuit Breaker | 15A | 1-Pole | 277V | 10kA | Bolt-On

Meet the Westinghouse EHB1015—a purpose-built 15A, 1-Pole, 277V bolt-on circuit breaker crafted for reliable protection in commercial and retrofit applications. When your panel requires exact compatibility, the EHB1015 delivers a secure, dependable solution that completes maintenance, retrofit, or replacement projects with confidence.

Key specifications at a glance

• Amperage: 15A
• Poles: 1-Pole
• Voltage: 277V
• Interrupting capacity: 10kA
• Mounting: Bolt-On
• Part reference: EHB1015

Why this breaker stands out

Unlike generic substitutes, the Westinghouse EHB1015 is designed to align with panels and distribution systems that specify a bolt-on, single-pole 277V protection device. The 10kA interrupt rating provides robust fault current protection in commercial environments, helping to minimize damage from overloads and short circuits. With exact part-number guidance, you’re far less likely to encounter fit or compatibility surprises during installation.

Ideal use cases

• Maintenance outages where a direct replacement is required for existing 277V circuits
• Retrofit projects upgrading electrical panels that mandate compatible EHB-series breakers
• New installations in commercial spaces that run lighting and equipment on 277V circuits
• Replacement of a failed one-pole breaker within a bolt-on panel configuration

How to verify fit and ensure a smooth install

Before ordering, confirm panel compatibility using the part number EHB1015 as the primary reference. Since this is a bolt-on, 1-pole device rated for 277V, it’s best suited for panels engineered to accept bolt-on units in single-circuit configurations. If your panel labeling calls out the EHB1015 or the equivalent Westinghouse bolt-on family, you’re aligned for an efficient replacement.

Installation and safety considerations

For best results, follow standard electrical safety practices: shut off power, verify de-energization, and use proper mounting hardware to secure the bolt-on connection. If you’re replacing a failed breaker in an active commercial panel, ensure the replacement is permitted by local electrical codes and performed by a qualified electrician. The EHB1015’s design supports a solid, vibration-resistant installation, helping to maintain consistent protection over time.

Whether you’re maintaining an existing installation or upgrading a panel to accommodate a dedicated 277V circuit, the Westinghouse EHB1015 delivers precise compatibility, reliable short-circuit protection, and the peace of mind that comes with a trusted brand.
