Eaton | BQL320 | Circuit Breaker | 20A | 3-Pole | 240V | Bolt-On

The Eaton BQL320 Circuit Breaker is a bolt-on, three-pole protection device engineered for 240V systems. With a 20A rating per pole, it delivers reliable overcurrent protection for panel upgrades, replacements, and ongoing maintenance in commercial and industrial environments.

Designed for seamless compatibility within Eaton’s BQL family, the BQL320 is identified by the part number and should be matched to panels and accessories that list the same reference. Before you order, confirm fit and ratings to ensure a perfect match for your specific enclosure.

Key benefits and what sets it apart

• Bolt-on mounting provides a secure, vibration-resistant connection that simplifies field installation and reduces the risk of loose connections.
• 3-Pole configuration enables simultaneous disconnection across all conductors in a 240V circuit, enhancing safety during maintenance and servicing.
• 20A per pole, 240V design tailored for typical 3‑phase or multiwire branch circuits found in commercial settings.
• Durable Eaton build built to withstand routine industrial use, with compatibility targeted to retrofit and replacement projects.

Ideal use scenarios

• Maintenance and service on existing electrical panels that require a precise BQL320 replacement.
• Retrofits where upgrading or standardizing on Eaton’s BQL line improves reliability and panel consistency.
• New installations in systems that demand a 3-pole, 240V breaker with a bolt-on mounting method.

Compatibility and installation tips

• Always verify fit and ratings against your panel’s labeling and the exact part number (BQL320) to ensure proper operation.
• Power should be fully OFF and the panel de-energized before replacement or installation.
• Confirm that the enclosure supports bolt-on breakers in the BQL family and follow the manufacturer’s torque and installation guidelines for secure mounting.
• Use in environments and panels that specify 240V, 3-pole protection to maximize safety and performance.

Ready for retrofit, replacement, or maintenance projects, the Eaton BQL320 delivers dependable circuit protection with a precise fit for Eaton-compatible panels. When you need a 20A, 3-pole, 240V bolt-on solution, the BQL320 is the clear choice for reliable, factory-approved performance.
