Product FAQs
7 answersIs the SCMD69600ANTH rated for 100 percent continuous current?
Yes, the SCMD prefix designates this as a 100 percent rated MD frame breaker. This allows the breaker to carry its full 600A continuous current rating without the standard 80 percent derating, provided it is installed in an enclosure approved for 100 percent operation.
Which Siemens panelboards are compatible with the SCMD69600ANTH?
This unit mount, bolt-on breaker is designed for use in Siemens Sentron Type P4, P5, and S5 panelboards, as well as compatible Siemens switchboards and enclosures.
How does the LSI electronic trip unit benefit my electrical system?
The solid state electronic trip unit features adjustable Long-Time, Short-Time, and Instantaneous (LSI) settings. This allows for precise trip curve shaping and selective coordination with upstream and downstream devices in complex distribution networks.
Does the SCMD69600ANTH include ground fault protection?
No, this specific model features an LSI trip unit (Long-Time, Short-Time, Instantaneous) which does not include ground fault protection. If your application requires equipment ground fault protection, you will need to source an LSIG variant.
What wire sizes are accepted by the lugs on this 600A breaker?
The standard lugs accommodate 1/0 AWG to 500 kcmil copper or aluminum conductors. Always verify the specific torque requirements listed on the breaker faceplate during installation to ensure a secure and compliant connection.
Can this breaker replace older ITE MD frame breakers?
Yes, Siemens acquired ITE and continues to manufacture the Sentron series. The SCMD69600ANTH can directly replace older ITE or Siemens-Allis breakers with the same MD frame size and specifications, though you should verify panel mounting hardware compatibility.
Is the SCMD69600ANTH a current-limiting circuit breaker?
Yes, this breaker features a current-limiting architecture that provides robust protection by quickly extinguishing faults. It delivers a high interrupting capacity of up to 200kA at 240V and 100kA at 480V to protect downstream equipment.
