The Square D QO330M150 circuit breaker delivers reliable, code‑compliant protection for 150‑amp circuits within compatible QO panelboards. This OEM replacement part is specifically suited for maintenance, retrofit, and replacement projects where exact specifications matter—ensuring a seamless swap with your existing Square D infrastructure.

Why the QO330M150 stands out

Engineered by Square D for the QO series, this 150 A circuit breaker is designed for straightforward installation in compatible panels, supporting long service life and predictable tripping behavior when overcurrent occurs. The 150 A rating is tailored to protect high‑demand circuits while minimizing nuisance trips when used with appropriately sized loads.

Key specifications

  • Amperage rating: 150 A
  • Series: QO (Square D)
  • Function: Overcurrent protection for the protected circuit
  • Compatibility note: Confirm fit and ratings before ordering. The part number is the best reference for compatibility.

Ideal use cases

  • Maintenance and servicing of existing Square D QO panelboards—swap in a like‑for‑like unit to restore protective coverage quickly.
  • Retrofit projects where a 150 A circuit needs reliable protection within a QO‑series panel without changing other hardware.
  • Replacement for failed or worn breakers in residential, commercial, or light industrial installations that rely on QO system compatibility.

Practical guidance for a smooth replacement

To ensure a successful upgrade or replacement, verify that the panel is part of the Square D QO family and that the 150 A rating matches the circuit being protected. Since configuration and compatibility hinge on the exact part reference, the QO330M150 designation is the most reliable reference when ordering.

When you’re looking for a precise, OEM‑quality 150‑amp breaker for QO panels, the QO330M150 delivers dependable protection, straightforward installation, and enduring performance—making maintenance, retrofit, and replacement projects simpler and more predictable.
