Square D Q232150 - 150A, 240VAC, 3-Pole, Circuit Breaker

Meet the Square D Q232150 — a rugged 150 A, 240 VAC, 3‑pole circuit breaker designed for demanding electrical environments. Built to protect 3‑phase power systems in panelboards, switchboards, and control panels, this device delivers reliable interruption of fault currents and safe operation in critical applications.

• Current rating: 150 A
• Voltage rating: 240 VAC
• Poles: 3‑Pole
• Breaker type: Circuit Breaker

Why this 3‑pole design matters

The 3‑pole configuration is purpose‑built for 3‑phase systems, letting you protect motors, drives, and other three‑phase equipment with a single, integrated solution. This simplifies wiring, reduces panel footprint, and streamlines maintenance in both new installations and retrofits.

Ideal applications

• Industrial and commercial panelboards that feed 3‑phase motors and equipment
• Motor control centers and switchboards requiring dependable overcurrent protection
• OEM control panels and distributed power architectures where compact, reliable protection is essential

What sets it apart

Designed specifically for environments where distribution panels and control centers demand robust protection, the Q232150 provides a straightforward solution for safeguarding three‑phase circuits at 240 VAC. Its 150 A rating is well-suited for common industrial feeders, enabling quick, predictable interruption when faults occur while supporting continuous operation of connected loads when circuits are healthy.

Practical considerations and tips

• Use in panelboards and control panels that support 3‑pole, 240 VAC circuit protection.
• Ideal for applications where a single device must protect multiple phases, reducing wiring complexity and potential points of failure.
• Regularly inspect for proper mounting, secure connections, and compliance with your facility’s electrical standards.
