The ITE CE3B060 is a 3 Pole thermal magnetic molded case circuit breaker with a current rating of 60 Amps and a voltage rating of 600VAC. It has an interrupting rating of 100kAIC at 480V. The CE3B060 has a bolt-on connection type and includes long time and instantaneous trip functions.
What is the modern replacement for the obsolete ITE CE3B060 circuit breaker?
The CE3B060 is a legacy Cordon style breaker. The documented Siemens replacement path for this CE frame progresses to the CLE frame and then to the modern Sentron CED frame. The direct cross reference is the CED63B060, which is mechanically and electrically interchangeable. Always confirm the replacement meets your specific fault current requirements.
Is the CE3B060 considered a current limiting circuit breaker?
Yes, the CE frame series is a current limiting molded case circuit breaker. It is designed to quickly interrupt high fault currents, limiting the peak let through current and protecting downstream equipment in systems with high available fault currents.
What is the mounting configuration for the CE3B060?
The CE3B060 utilizes a bolt-on connection. It fastens directly to the panelboard busbars using threaded hardware, which ensures a secure, high contact pressure connection that resists loosening from thermal cycling and vibration in industrial applications.
Will the CE3B060 fit in a standard Siemens Sentron panelboard?
The CE3B060 is an older ITE frame. While it shares physical dimensions with the modern Siemens ED frame family, you must check the interior labeling of your specific panelboard. The panel must explicitly list the CE frame as an acceptable breaker type to maintain UL listing and code compliance.
How does the thermal magnetic trip unit in the CE3B060 operate?
The breaker features long time and instantaneous (LI) trip functions. The thermal bimetal element provides delayed tripping for sustained overloads, preventing nuisance trips from temporary surges. The magnetic element provides an instantaneous trip response to clear severe short circuits quickly.
