Description
Mounting securely into Siemens Sentron panelboards, the CED62B050 is a 50-amp, two-pole current-limiting molded case circuit breaker. Designed to minimize let-through energy during a fault, it offers premium protection for industrial electrical distribution networks. This ED frame breaker utilizes a bolt-on design for integration into compatible switchboards. It is equipped with a non-interchangeable thermal-magnetic trip unit, is rated for reverse feed, and delivers 200kAIC at 480VAC.Specifications

Product FAQs
8 answersWhat panelboards are compatible with the CED62B050?
This bolt-on breaker is designed for use in Siemens Sentron panelboards, including P1, P2, and P3 models, as well as compatible Siemens switchboards.
Can the CED62B050 replace older Siemens or ITE breakers?
Yes, the CED6 series is often used as a direct replacement for legacy CE and CLE breakers in existing ED frame installations. This allows you to maintain your current panel configuration without retrofitting.
What does the current limiting designation mean for this breaker?
As a current limiting breaker, it is engineered to reduce the peak fault current and let-through energy before the circuit opens. This provides enhanced protection for downstream conductors and equipment during a short circuit.
Is the CED62B050 suitable for DC applications?
Yes, in addition to its AC ratings, this breaker is rated for use in DC systems up to 250VDC, providing a 30kA interrupting capacity at that voltage.
What size and type of wire can be used with the load lugs on this breaker?
The included load lugs accept 10 AWG to 1/0 AWG conductors and are compatible with both copper (Cu) and aluminum (Al) wire.
How is this breaker mounted in the panel?
The CED62B050 features a bolt-on connection type, meaning it securely bolts directly to the busbars in compatible Siemens panelboards and switchboards.
What type of protection does the LI trip function provide?
The LI (Long-Time, Instantaneous) thermal magnetic trip unit provides two types of protection. The thermal element responds to prolonged overloads (Long-Time), while the magnetic element trips immediately during a short circuit (Instantaneous).
What does the C in the CED6 prefix indicate?
The C indicates Siemens current limiting construction, which provides higher interrupting ratings and fault mitigation compared to standard ED6 frame breakers.
