Square D | QOB230EPD2100 | Circuit Breaker | 30A | 2-Pole | 240V

Square D QOB230EPD2100 is a purpose-built 30A, 2-Pole, 240V circuit breaker designed for maintenance, retrofit, and replacement projects where exact specifications matter. Built to protect electrical circuits in Square D panels, this unit delivers reliable overcurrent protection when your system demands precise component matching.

Key specifications

• Amperage: 30A
• Poles: 2-Pole
• Voltage: 240V
• Part reference: QOB230EPD2100 — best compatibility reference; always confirm fit and ratings before ordering

Why this breaker fits your project

When you’re maintaining, retrofitting, or replacing an aging panel, matching the exact part number is the quickest way to ensure proper fit, electrical clearance, and reliable operation. The QOB230EPD2100 is purpose-built for Square D installations and aligns with the standard 240V circuits in many residential and light commercial applications. Its 30-amp rating makes it suitable for circuits that require robust protection without unnecessary nuisance tripping, helping to safeguard wiring and connected equipment.

Ideal use cases

• Retrofit projects in older Square D panels where the original 30A 2-Pole breaker has reached end of life
• Maintenance swaps to restore original protection levels without modifying downstream wiring
• Replacement scenarios where exact part reference (QOB230EPD2100) ensures compatibility with bus stabs, mounting, and slot dimensions
• Commercial and light-industrial settings needing dependable 240V protection for multi-wire branch circuits

How to verify compatibility

Use the part number as your primary reference. Before ordering, double-check:

• The panel model and line/load configuration must support a 2-Pole, 30A unit
• The circuit breaker must be rated for 240V operation in your application
• Physical fitment in the panel’s available slot and proper mounting orientation

Practical tips for install and maintenance

• Power down the main and verify all downstream circuits are de-energized before removal or installation
• Handle the breaker carefully to avoid damaging the bus connections and mounting hardware
• Store spare units in a dry, cool environment to prevent corrosion of connection points

Choosing the QOB230EPD2100 ensures you’re aligning with the exact specification you need for a reliable, code-compliant protection solution. If your project requires precise matching of amperage, pole count, and voltage, this 30A, 2-Pole, 240V breaker is a straightforward, trustworthy choice that helps you maintain electrical safety and system integrity.
