Siemens CED63B080 - 80 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Introducing the Siemens CED63B080—a dependable 80 A, 600 V, 3-pole bolt-on molded case circuit breaker designed to deliver robust branch circuit protection in panelboards and load centers. Its secure bolt-on mounting creates a rigid, vibration-resistant bus connection, ideal for environments where equipment vibration or movement is a factor.

The thermal-magnetic trip unit offers stable, repeatable protection by combining fast magnetic action for short circuits with precise thermal control for overloads. This balance helps minimize nuisance trips while guarding downstream circuits and connected equipment against damaging faults, from lighting and feeders to motors and compressors.

With a 3-pole configuration, this breaker ensures all three phases trip together, preserving three-phase system integrity in commercial and light industrial applications. It is specifically engineered to be compatible with matching Siemens OEM load centers and panelboards, simplifying installation and ensuring reliable performance in your existing or new Siemens-compatible electrical distribution system.
