Product FAQs
7 answersWhich Siemens panelboards are compatible with the CLD63B600 breaker?
This LD-frame breaker is designed for use in Siemens Sentron Type P4 and P5 panelboards, as well as compatible Siemens switchboards and motor control centers.
What are the wire size requirements for the CLD63B600?
When equipped with the required TA2J6500 lugs, the breaker accepts two 3/0 AWG to 500 kcmil copper conductors, or two 4/0 AWG to 500 kcmil aluminum conductors per phase.
Is this a plug-in or bolt-on breaker?
The CLD63B600 is a unit mount, bolt-on circuit breaker. It requires bolted connections to the bus and is not designed for plug-in load centers.
What does the 'C' in the CLD63B600 part number signify?
The 'C' designates it as the ultra-high interrupting capacity tier within the Sentron LD frame family, providing a 150kAIC rating at 480VAC and 100kAIC at 600VAC.
Can the trip settings on this 600A breaker be adjusted?
The thermal (long-time) trip is fixed at 600 amps, but the magnetic (instantaneous) trip is adjustable to allow for proper coordination with downstream devices and motor inrush currents.
Is the Siemens CLD63B600 a direct replacement for the ITE CLD63B600?
Yes. Siemens acquired ITE and continued manufacturing the Sentron series under the Siemens brand. An ITE-branded CLD63B600 shares the exact same physical dimensions and electrical characteristics as the current Siemens version.
Is this breaker suitable for DC voltage systems?
Yes, the CLD63B600 is rated for DC applications up to 500VDC, where it provides an interrupting capacity of 50kA.
