Square D | EHB14030EPD | Circuit Breaker | 30A | 1-Pole | 277V | 14kA | Bolt-On

The Square D EHB14030EPD is a 30-amp, 1-pole bolt-on circuit breaker built to deliver dependable protection for 277-volt circuits in commercial and industrial panels. Designed for maintenance, retrofit, and replacement projects, it slots into compatible Square D bolt-on panel configurations to keep critical electrical systems protected and compliant.

Key specifications

• Amperage: 30 A
• Poles: 1-Pole
• Voltage: 277 V
• Interrupting capacity: 14 kA
• Mounting style: Bolt-On
• Part number: EHB14030EPD

Why this Square D 30A bolt-on breaker stands out

Unlike plug-in breakers designed for different panel families, this bolt-on model offers a robust, vibration-resistant connection ideal for dense electrical panels where space is at a premium. The 14 kA interrupting rating provides ample protection for typical commercial fault conditions, helping limit damage and downtime when a short circuit occurs on 277V circuits.

Use cases and ideal applications

• Maintenance and retrofit projects in commercial buildings with 277V distribution.
• Replacement for compatible Square D bolt-on panels requiring a 30 A, 1-pole breaker.
• Protection for 277V lighting circuits, HVAC feeders, or other single-pole loads in industrial settings.

Compatibility and installation tips

To ensure a seamless fit, verify that your panel accepts bolt-on, 1-pole EHB breakers and that the ratings match your circuit requirements. This part is specifically identified by the reference EHB14030EPD, so use that number when confirming compatibility with your panel model.

• Notes: Confirm fit and ratings before ordering. Part number is the best reference for compatibility.
• Follow standard safety practices: power down the panel, discharge stored energy, and securely fasten the breaker to the panel bus with the panel manufacturer's torque specifications.

Choosing the right breaker is about matching the application, not just the amperage. For bolt-on Square D panels configured for EHB family breakers, the EHB14030EPD delivers reliable, consistent protection for 30-amp circuits at 277 volts, backed by a widely supported form factor and a proven track record in commercial installations.
