Square D QOT22030 30A 4-Pole 240 V Circuit Breaker

The Square D QOT22030 stands out as a robust protection solution for 240-volt circuits in compatible Square D panels. With a 30-amp rating and four poles, this breaker is engineered to safely interrupt multiple live paths, delivering reliable, synchronized shutdown of all conductors when protection is required. If your electrical setup requires a four-pole device to guard complex 240V or multi-wire branch circuits, the QOT22030 is purpose-built to deliver precise, dependable performance.

Key specifications

• Part Number: QOT22030
• Current rating: 30 A
• Poles: 4
• Voltage rating: 240 V
• Series: Square D QOT (4-pole, 240V)

Why the 4-pole design matters

A four-pole configuration provides comprehensive protection across all conductors in applicable 240V or multi-wire applications. This means safer disconnection of multiple lines for gear like large motors, compressors, or multi-wire branch circuits, reducing the risk of partial energization during maintenance and improving overall system safety.

• Simultaneous disconnection of all lines for complete de-energization
• Enhanced protection for complex or three-phase configurations requiring additional poles
• Consistent trip performance matched to Square D panel specifications

Ideal use cases

• Central air conditioning and large heating/cooling equipment that run on 240V
• Industrial or commercial motors and compressors that benefit from multi-pole protection
• Multi-wire branch circuits where a full disconnect of all conductors is desirable for service work
• Applications in Square D load centers and panels that accept QOT-type breakers

Installation and compatibility tips

• Ensure your panel is compatible with QOT-series breakers and accepts four-pole devices
• Follow standard safety practices: shut off main power, verify absence of voltage, and securely seat the breaker into the bus
• Torque connections to the manufacturer’s specifications and recheck after initial energization
• Label the circuit clearly to reflect the protected load and ensure quick, safe maintenance future-use

Choose the Square D QOT22030 30A 4-Pole 240 V Circuit Breaker for dependable, precise protection of demanding 240V circuits. It’s a purpose-built solution crafted to meet the needs of professional electrical installations, delivering safety, reliability, and compatibility with Square D panel systems.
