Square D QOB260 - 60 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Discover the Square D QOB260 — a 60A, 240V, 2-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built by Square D, it pairs rugged construction with precise thermal-magnetic protection to keep critical circuits safe in busy commercial spaces and homes.

Smart design for reliable, vibration-prone installations

• Bolt-on mounting provides a rigid, vibration-resistant bus connection that stays tight even in environments with equipment vibration or temperature fluctuations.
• Thermal-magnetic trip unit combines heat and magnetic sensing to deliver stable, repeatable protection, reducing nuisance trips while responding rapidly to short circuits.
• 2-pole, 60A, 240V rating is suitable for standard 240V branch circuits, including multi-wire setups when paired with the correct bus and enclosure.
• OEM compatibility designed to pair with matching Square D load centers and panelboards for straightforward, plug-and-play installation.
• Versatile applications ideal for residential, commercial, and light industrial panels where reliable protection is essential.

Why this matters: in electrical distribution, a breaker’s role is to interrupt current before wiring, devices, and people are endangered. The QOB260’s thermal-magnetic technology means that overloads (like a miswired load or a fault) trigger the trip predictably, while a parallel short-circuit draws a high magnetic force that snaps open the circuit within milliseconds. That combination minimizes downtime and protects transformers, feeders, and sensitive equipment.

Practical use cases

• New installations in panelboards and load centers that require a robust bolt-on solution.
• Upgrades or replacements in residential service panels and light commercial distribution boards.
• Spare-part stocking for field service teams maintaining Square D systems.

Who should buy this: electricians, facilities managers, and maintenance technicians stocking reliable, OEM-aligned protection for Square D panelboards and load centers. If you’re upgrading from a non-bolt-on solution or expanding a 240V distribution, the QOB260 delivers predictable protection with a familiar mounting approach and seamless compatibility.

Notes for installation: always shut off power and follow local electrical codes. Use the QOB260 only in compatible Square D panelboards and load centers. Ensure correct torque and mounting procedures per the manufacturer’s instructions to maintain fault current protection and warranty compliance.

With the Square D QOB260, you get a dedicated, dependable bolt-on breaker that protects your 240V circuits with a precise thermal-magnetic trip, a stable bus connection, and OEM-aligned compatibility — a practical choice for reliable electrical distribution in any modern building.
