Square D QOB260EPD - 60 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Meet the Square D QOB260EPD — a 60A, 240V, 2-pole bolt-on molded case circuit breaker designed to shield panelboards and loadcenters from overcurrent and short-circuit events. Built for reliability in demanding environments, this device combines rugged construction with precise protection to keep electrical systems safe and compliant.

• Secure bolt-on mounting: A rigid, vibration-resistant bus connection minimizes movement and loosening, delivering dependable protection even in installations with equipment start-up and vibration.
• Thermal-magnetic trip unit: Delivers stable, repeatable protection by reacting to both sustained overcurrent and instantaneous faults, reducing nuisance trips while safeguarding wiring and connected loads.
• 2-pole, 60A at 240V: Ensures simultaneous disconnection of both conductors for safer isolation of branch circuits on typical residential, commercial, and light industrial panels.
• OEM-compatible: Engineered to fit and function with matching Square D OEM load centers and panelboards for a seamless replacement or system expansion.
• Versatile application: Ideal for protecting lighting circuits, receptacle runs, pumps, HVAC controls, and other branch loads in homes, small businesses, and service entrances requiring robust overcurrent protection.

Why this design matters in real-world installations: the bolt-on format provides a solid, long-lasting connection to the bus bars, critical in environments with vibration or frequent cycling. The molded case construction offers strong insulation and durability, while the thermal-magnetic trip unit delivers reliable protection without complicating adjustments or maintenance. Paired with compatible OEM panelboards, the QOB260EPD delivers a cohesive protection solution that’s straightforward to integrate into existing electrical distributions.

Ideal for:

• Residential panel configurations needing reliable 60A protection for branches
• Commercial electrical rooms with lighting, receptacle circuits, and small equipment loads
• Light industrial applications where robust overcurrent and short-circuit protection is required

Practical tips for use:

• Confirm that your panelboard supports bolt-on breakers and that the QOB260EPD is the correct type for your OEM panel’s bus connections.
• Pair this 60A, 240V 2-pole breaker with circuits that truly require two-pole isolation to meet code and safety standards.
• When replacing an existing breaker, ensure the replacement matches the panel’s specifications and follow the manufacturer’s torque guidance for mounting hardware to ensure a solid connection.
• Keep the load center’s overall protection scheme in mind—use this breaker to align with your distribution plan and to maintain consistent short-circuit protection across the panel.
