Description
Part of the legacy SENTRON family, this 3-pole, 600A molded case circuit breaker provides robust thermal-magnetic protection. It is engineered to safeguard commercial and industrial electrical systems against overloads and short circuits. Designed for unit mounting, it installs into classic ITE and Siemens panelboards or motor control centers. Utilizing this exact replacement eliminates the downtime and modification costs associated with upgrading to the newer LMD63B600 breaker.Specifications

Product FAQs
6 answersWhat equipment is the Siemens ET-600 compatible with?
It is designed for unit mounting in legacy ITE and Siemens switchboards, motor control centers, and panelboards.
What is the modern replacement for the legacy ET-600 circuit breaker?
The newer LMD63B600 is often used as a modern replacement for the ET-600. However, upgrading to the LMD frame may require enclosure modifications, whereas using an exact ET-600 replacement avoids retrofit downtime.
What wire sizes are accepted by the lugs on the ET-600?
The standard lugs accept two conductors per phase, ranging from 3/0 AWG to 500 kcmil for both aluminum and copper wire.
What are the adjustable trip settings on this breaker?
The ET-600 features a thermal magnetic trip unit with fixed thermal protection for long-time overloads and an adjustable magnetic trip for instantaneous short-circuit protection.
Can the ET-600 be used in DC applications?
Yes, this breaker is rated for up to 250V DC systems, providing an interrupting capacity of 14kA at that voltage.
How is the ET-600 mounted within an enclosure?
This is a unit-mount circuit breaker, meaning it bolts directly to the mounting pan or structure within the enclosure rather than plugging onto a busbar.
