Square D QOB115EPD - 15 A, 120 V, 1-Pole Bolt-On Circuit Breaker | AmpState

Square D QOB115EPD — 15A, 120V, 1-Pole Bolt-On Molded Case Circuit Breaker delivers dependable branch-circuit protection for panelboards and load centers. Built for residential, commercial, and light industrial applications, this unit guards against overcurrent and short circuits with a secure bolt-on mounting that creates a rigid, vibration-resistant bus connection.

The QOB115EPD uses a thermal-magnetic trip unit, delivering stable, repeatable protection across a wide range of operating conditions. The thermal element responds to gradual heating, while the magnetic element delivers instantaneous response to high-magnitude faults, reducing the risk of damage to wiring and downstream devices.

• Secure bolt-on mounting: ensures a robust, vibration-resistant connection that stays tight during operation and service.
• Thermal-magnetic protection: reliable trip behavior for both sustained overloads and sudden short circuits.
• 120V compatibility: specifically suited for standard branch circuits such as lighting, outlets, and small equipment.
• 1-pole design: single-phase protection ideal for typical residential and light commercial panels.
• OEM-compatible installation: designed to pair with matching Square D OEM load centers and panelboards for a seamless replacement or upgrade.
• Versatile applicative range: suitable for residential homes, commercial spaces, and light industrial environments where reliable circuit protection matters.

Why this bolt-on breaker stands out: it combines a rugged, vibration-resistant mounting with precise protection characteristics, ensuring your electrical system remains safe and reliable under normal operation and fault conditions. If you’re upgrading an existing panel or installing a new one that requires bolt-on protection, the QOB115EPD is a straightforward, dependable choice that supports long-term service life.
