Square D QO330SWN is a 30 amp, 3-pole, 240V plug-in circuit breaker designed for reliable protection in Square D panel systems. This unit shines in maintenance, retrofit, and replacement projects where precise specifications and a straightforward install matter, helping you keep critical circuits safely powered.
- Amperage: 30A
- Poles: 3-Pole
- Voltage: 240V
- Mounting: Plug-In
- Reference: Part number QO330SWN for compatibility verification
Why this matters in practice: the 3-pole, 240V configuration provides coordinated protection across all hot legs for multi-wire branch circuits and motor loads, reducing the risk of partial trips and wiring damage. The plug-in design enables faster, cleaner replacements in compatible Square D panels, minimizing downtime and simplifying service calls for electricians and maintenance teams.
Ideal applications
- Residential and light commercial panel upgrades where a 30A, 240V circuit needs protection
- Retrofit of aging or worn-out breakers in existing Square D QO panel environments
- Replacement for circuits that require a precise 30A 3-pole solution to safeguard equipment and wiring
Important note: Before ordering, confirm fit and ratings. The part number QO330SWN is the best reference for compatibility with your Square D QO panel system to ensure a seamless plug-in installation.
