Siemens CED63B050 - 50 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

When safeguarding electrical distribution, you need a breaker that stays put, protects reliably, and plays nicely with your Siemens panel ecosystem. The Siemens CED63B050 50A, 600V, 3-pole bolt-on molded case circuit breaker is engineered for durable branch-circuit protection in panelboards and loadcenters. Built for environments where vibration and load vary, it delivers consistent, repeatable protection you can count on.

• Secure bolt-on mounting provides a rigid, vibration-resistant connection to the bus, reducing loosening and ensuring stable electrical performance in demanding installer and service conditions.
• Thermal-magnetic trip unit delivers fast, predictable responses to overloads and short circuits, minimizing nuisance trips while preserving system safety.
• 3-pole design supports three-phase circuits, making it ideal for commercial or light industrial panelboards and loadcenters that require reliable 3-phase protection.
• 50A, 600V rating aligns with common industrial and commercial electrical distributions, providing robust protection for medium-load applications without oversizing equipment.
• OEM-compatible integration is designed to pair with matching Siemens loadcenters and panelboards for a seamless, factory-prescribed protection solution.
• Durable molded-case construction stands up to installation, maintenance, and steady-state operation in busy electrical rooms.
• Versatile for multiple sectors—suitable for residential service centers, commercial distribution panels, and light industrial equipment feeds where dependable overcurrent protection matters.

What problems does this breaker solve? It provides reliable branch circuit overcurrent protection and fast short-circuit disconnection, helping prevent damage to wiring, reducers, and connected equipment. The bolt-on design minimizes connection failures due to vibration or movement, while the thermal-magnetic trip ensures consistent protection curves across varying loads and ambient conditions.

Ideal use cases include:

• Secondary distribution panels in small to mid-size commercial spaces
• Light industrial electrical rooms feeding motors or multi-line equipment
• Residential or mixed-use panelboards that require 3-pole, 50A protection in 3-phase configurations
• Upgrade or replacement installations in Siemens OEM-loaded panelboard ecosystems for reliable, matched protection
