Siemens CED63S100 A - 100 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

When reliability matters for 3‑phase systems, the Siemens CED63S100A stands out as a purpose-built solution for branch circuit overcurrent and short‑circuit protection in panelboards and load centers. This 3‑pole bolt‑on molded case breaker combines rugged construction with precise protection, designed to keep commercial, light industrial, and even certain residential installations safe and compliant.

• Secure bolt‑on mounting for a rigid, vibration‑resistant bus connection that stays consistent through compressor starts, HVAC cycles, and general panel activity.
• Thermal‑magnetic trip unit delivers stable, repeatable protection performance, responding to both sustained overloads and high‑instantaneous fault currents without nuisance trips.
• OEM‑compatible design built to work with matching Siemens OEM load centers and panelboards, helping you maintain listing compatibility and streamlined installs.
• Three‑pole, 100 A, 600 V rating ideal for protecting three‑phase circuits and heavier branch circuits common in commercial and light industrial applications.
• Molded case construction combines durability with compact form, making it a reliable choice for panel inventories and field replacements alike.

Why this Siemens breaker is a smart pick

In panel‑board and load‑center environments, a bolt‑on molded case breaker like the CED63S100A minimizes vibration and connection looseness, which can degrade protection over time. The thermal‑magnetic trip mechanism provides fast, consistent response to short circuits and overloads, helping you meet safety standards and electrical codes with confidence. Its 3‑pole design simplifies integration into 3‑phase systems, while the 100 A rating gives you the right level of protection for mid‑sized distributions without overshooting your load calculations.

Ideal applications and use cases

• New installations in commercial spaces needing reliable three‑phase protection.
• Replaceable or upgrade scenarios in existing Siemens OEM panelboards and load centers.
• Light industrial electrical bays where consistent trip characteristics reduce downtime and service calls.
• Residential developments with 3‑phase distribution requirements or multi‑meter configurations that require robust branch protection.
