Siemens CED63A100L - 100 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Siemens CED63A100L is a 100A, 600V, 3-pole bolt-on molded case circuit breaker built to protect panelboards and loadcenters from overcurrent and short circuits. Designed for reliability in demanding environments, this unit combines secure mounting with precise trip performance to keep electrical systems safe and scalable.

• Secure bolt-on mounting: provides a rigid, vibration-resistant bus connection that maintains electrical integrity in installations subject to movement or equipment vibration.
• Thermal-magnetic trip unit: delivers stable, repeatable protection — the thermal element handles overloads, while the magnetic element provides instantaneous trips for damaging short circuits.
• OEM-compatible: engineered to be compatible with matching Siemens OEM loadcenters and panelboards, ensuring a proper fit and predictable performance.
• Three-pole protection: 3-pole design protects 3-phase circuits common in commercial and light industrial applications.
• Wide application range: suitable for residential, commercial, and light industrial panel installations where dependable branch-circuit protection is essential.
