The Square D QOB135 is a 1-pole, 35A, 120V bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built for solid, vibration-free performance, its bolt-on mounting creates a rigid connection to the bus, helping to minimize loosening and maintain consistent electrical contact over time.

  • Secure bolt-on mounting provides a rigid, vibration-resistant bus connection for reliable, long-lasting protection.
  • Thermal-magnetic trip unit delivers stable, repeatable protection—fast response to short circuits and sensible protection against sustained overloads.
  • 1-pole, 35A at 120V is ideal for single-phase branch circuits requiring robust protection without excessive interruption.
  • OEM compatibility designed to work with matching Square D load centers and panelboards, ensuring proper fit and performance.
  • Versatile for multiple environments suitable for residential, commercial, and light industrial applications where reliable circuit protection is essential.

What it protects and why it matters: the QOB135 safeguards individual branch circuits from overcurrent and short circuits, helping prevent wiring damage, nuisance trips, and potential electrical fires. The combination of a thermal (overload) and magnetic (short-circuit) mechanism provides a balanced, predictable response that aligns with real-world electrical loads.

Ideal use scenarios

  • Residential panels and subpanels requiring dependable single-pole protection for critical lighting or receptacle circuits.
  • Commercial installations where compact, bolt-on breakers fit the panel design and load requirements.
  • Light industrial setups that demand robust protection for dedicated circuits operating at 120V.
  • Upgrading or replacing existing Square D QOB135 units in compatible panelboards to maintain consistent protection performance.
