Siemens QF115H - 15 A, 120 V, 1-Pole Plug-In Circuit Breaker | AmpState

The Siemens QF115H 15A, 120V, 1-pole Plug-In Circuit Breaker is a durable, do-it-now solution for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Engineered for quick installation and reliable performance, this molded case breaker is built to handle the demands of residential, commercial, and light industrial environments.

Why the Siemens QF115H Stands Out

• Fast plug-in connection for rapid installation and hassle-free replacement, reducing downtime during panel upgrades or service work.
• Thermal-magnetic trip unit provides stable, repeatable protection by accurately sensing both overloads and short-circuits, helping prevent nuisance trips and protect wiring.
• OEM-compatible design ensures seamless integration with matching Siemens OEM load centers and panelboards, minimizing compatibility concerns during installation or retrofits.
• Versatile application suitable for residential panels, commercial electrical rooms, and light industrial circuits that require reliable 15A protection at 120V.

What Problems It Solves

Whether you’re upgrading an aging panel, adding a new branch circuit, or performing routine maintenance, the QF115H delivers predictable protection. The thermally responsive element handles sustained overloads, while the magnetic element quickly interrupts severe short circuits. This combination helps guard wiring, outlets, and connected devices from damage, while keeping your electrical system running smoothly.

Ideal Use Scenarios

• Residential service panels replacing aging 15A breakers for safer, faster upgrades.
• Commercial load centers needing reliable 120V, single-pole protection on branch circuits.
• Light industrial circuits where quick plug-in replacements minimize downtime in maintenance windows.
• retrofit projects requiring OEM-compatible components to maintain panel integrity and warranty compliance.
