Square D QOB230 - 30A, 240VAC, 2-Pole, Circuit Breaker

Meet the Square D QOB230—a 30A, 240VAC, 2-pole circuit breaker designed to deliver dependable overcurrent protection in demanding electrical environments. The two-pole configuration protects both conductors in multi-wire circuits, enabling safe, coordinated shutdown for panel layouts, switchboards, and control panels.

Key specifications you can rely on

• Current rating: 30A
• Voltage rating: 240VAC
• Poles: 2-Pole
• Breaker type: Circuit Breaker (Square D QOB series)
• Applications: panelboards, switchboards, and control panels

Built for industrial, commercial, and OEM applications, this breaker delivers dependable protection in distribution panels and motor control centers. It helps safeguard electrical systems from overloads and short circuits, supporting equipment uptime and safe operation in busy facilities.

Why this 2-pole design matters

• Simultaneous disconnection of both conductors reduces fault and arc risks in shared circuits.
• Compact, robust form factor fits tightly packed panel spaces without compromising protection.
• Reliable integration with Square D distribution products, streamlining maintenance and replacement.
• Effective protection for motor feeders, feeders to critical loads, and other control panel subsystems.

Ideal for

technicians, engineers, and facility managers working in industrial settings, commercial buildings, and OEM equipment assembly who require consistent, trustworthy overcurrent protection. Use the QOB230 in distribution panels and motor control centers to maintain safe operation and reduce downtime.

Practical installation and usage tips

• Verify panel compatibility with 2-pole QOB-type breakers and confirm that 30A at 240V aligns with your circuit design.
• Leverage the 2-pole configuration to efficiently protect paired conductors in multi-wire circuits.
• Keep spare units on hand to minimize downtime during routine maintenance or fault replacement.
