Siemens SCMD69800ANGTH - 800 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Siemens SCMD69800ANGTH is an 800A, 600V, 3-pole bolt-on molded case circuit breaker engineered to protect branch circuits from overcurrent and short circuits in panelboards and load centers. Built for reliability in demanding electrical environments, this unit pairs heavy-duty protection with a secure, vibration-resistant mount.

Secure, vibration-resistant bolt-on mounting

The bolt-on design provides a rigid connection to the bus, reducing movement that can compromise protection over time. This makes the SCMD69800ANGTH a smart choice for installations where panels may experience vibration or physical movement, helping maintain consistent performance and long-term reliability.

Stable, repeatable protection with a thermal-magnetic trip

The integrated thermal-magnetic trip unit combines two protection modes: the thermal element responds to gradual overloads with predictable timing, while the magnetic element delivers instantaneous response to short-circuit events. This dual-action approach minimizes nuisance trips and preserves system uptime in busy commercial or light industrial settings.

OEM-compatible and easy to integrate

Designed to work seamlessly with matching Siemens OEM load centers and panelboards, ensuring proper protection coordination and straightforward integration into existing electrical distribution systems.
