Siemens CED63A005 - 5 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Siemens CED63A005 is a 5 A, 600 V, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch-circuit protection in panelboards and load centers. Built for steady performance in demanding electrical environments, this device helps keep circuits safe from overcurrent and short-circuit events without compromising on reliability or ease of installation.

Why this breaker stands out

• Secure bolt-on mounting provides a rigid, vibration-resistant connection to the bus bars, reducing the risk of loose connections in panels that experience vibration or frequent access.
• Thermal-magnetic trip unit combines temperature-sensitive and magnetic trip mechanisms for stable, repeatable protection across varying loads and temperatures. This means faster response to true faults while minimizing nuisance trips on normal operation.
• OEM-compatible design matches Siemens load centers and panelboards, ensuring proper fit, coordinated protection, and straightforward replacement when upgrading or servicing panels.
• Three-pole configuration protects three-phase circuits up to 600 V, making it well-suited for commercial and light industrial equipment, motor loads, and distributed lighting or power systems.
• Exact amperage rating of 5 A provides precise control for sensitive equipment and control circuits, helping to prevent unnecessary disconnections while maintaining safety margins.
• Versatile for multiple environments ideal for residential, commercial, and light industrial applications where reliable branch-circuit protection is essential.

Ideal use scenarios

• Three-phase protection for small-to-mid-sized commercial panels managing lighting, receptacle banks, and HVAC-related circuits.
• Motor and equipment circuits in light industrial settings where stable trip characteristics reduce downtime and equipment wear.
• Upgrading or replacing aging breakers in Siemens OEM panel systems to maintain compatibility and predictable performance.
