Siemens SND69800 A - 800 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Siemens SND69800A is a high-capacity, 800A, 600V, 3-pole bolt-on molded case circuit breaker designed to protect branch circuits with precision and reliability. Built for demanding panelboards and load centers, it delivers dependable overcurrent and short-circuit protection where it matters most—in modern electrical distribution systems.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, helping prevent loose connections and arcing in environments with equipment vibration or heavy loads.
• Thermal-magnetic trip unit combines thermal protection for gradual overload sensing with a magnetic trip for instantaneous response to severe short circuits, delivering stable, repeatable protection performance.
• OEM-compatible design is engineered to work with matching Siemens OEM load centers and panelboards, ensuring seamless integration and consistent protection across existing systems.
• Three-pole configuration supports 3-phase installation for residential, commercial, and light industrial applications, making it ideal for motor loads, HVAC systems, and other multi-phase equipment.

Who this is for: electrical professionals upgrading or expanding panelboards, facilities managers replacing worn breakers in commercial or light industrial settings, and installers seeking a robust bolt-on solution that won’t complicate panel compatibility. The SND69800A is especially well-suited for panels that require a secure, high-current disconnect with reliable short-circuit protection and minimal maintenance.

Why choose the SND69800A over other options? Its bolt-on mounting delivers a sturdier connection than plug-in alternatives in vibration-prone environments, while the thermal-magnetic trip provides precise, predictable trips—reducing nuisance outages and protecting equipment. When you need a 3-pole, 800A breaker that aligns with Siemens load centers, this model offers a cohesive, field-proven solution.
