Who should consider the Square D QOB130EPD? If you’re upgrading or replacing a failed breaker in compatible Square D panels, this 1-pole bolt-on option provides a rugged, secure connection for a single branch circuit—ideal for lighting, outlets, or dedicated appliances in homes, small offices, retail spaces, or light industrial environments.

Why choose bolt-on in your panel? The bolt-on mounting delivers a sturdier mechanical connection in environments with vibration or movement, reducing the risk of loose connections over time. The thermal-magnetic trip mechanism kicks in decisively when overcurrent or a short circuit occurs, helping prevent damage to wiring and equipment.

Practical guidance for selection and use: ensure your panelboard or loadcenter is compatible with Square D bolt-on breakers, and verify the 30A, 120V single-pole configuration matches your circuit requirements. For best results, pair the QOB130EPD with the corresponding OEM components in your Square D system, and perform any installation or replacement with the power fully disconnected and by a qualified electrician.

When you’re shopping for reliable protection for single-pole circuits in residential, commercial, or light industrial applications, the Square D QOB130EPD from AmpState offers a proven, OEM-compatible solution that emphasizes durable mounting, precise protection, and straightforward compatibility with your existing panel infrastructure.
