Key Features

• 30 Amp continuous current rating
• 3‑pole design for three‑wire 120/240 VAC systems
• Plug‑in QO series form factor for compatible load centers
• Shunt trip feature provides remote trip capability
• 10 kAIC interrupting rating

Function and purpose

This QO3301021 breaker provides overcurrent protection and common‑trip disconnection for three‑pole circuits in 120/240 VAC systems. The integrated shunt trip enables the breaker to be tripped remotely by applying a control voltage to the shunt trip coil.

• Protects three‑pole loads with a single device and common trip operation
• Shunt trip allows external control (remote trip) for safety or interlock applications

Electrical ratings and performance

Rated electrical specifications identify the breaker for use on 120/240 VAC systems with a 30 amp continuous rating and a 10 kAIC interrupting capacity.

• Nominal voltage: 120/240 VAC
• Nominal current: 30 A
• Interrupting rating: 10 kAIC

Panel and mounting compatibility

The QO3301021 uses the Square D QO plug‑in form factor designed for QO series load centers and distribution panels. Confirm panel model compatibility before installation.

• Plug‑in mounting for QO series panels
• Intended for use where Square D QO breakers are specified

Shunt trip capability

The breaker includes a shunt trip mechanism that permits remote tripping when the shunt coil is energized. The shunt trip provides an electrical means to open the breaker without manual toggling.

• Enables remote or automatic disconnection via an external control circuit
• Use appropriate control voltage and wiring per equipment and local electrical codes

Before You Order

Confirm the model number and quantity required before ordering. Verify compatibility with your Square D QO load center, required shunt trip control voltage, and local electrical code requirements.

• Confirm panel type accepts QO plug‑in breakers
• Confirm shunt trip control voltage and wiring method for your application
• Provide model number QO3301021 when requesting a quote
