Product FAQs
7 answersWhat equipment is compatible with the SJD69400NGTH circuit breaker?
The SJD69400NGTH is designed for installation in Siemens Sentron Type P4, P5, and SPP panelboards, as well as Siemens switchboards and motor control centers.
Can the SJD69400NGTH be reverse fed?
Yes. Because it is built with a non-interchangeable trip unit, the SJD69400NGTH is UL listed for reverse connection applications.
What protection functions are included in the SJD69400NGTH trip unit?
This breaker features a solid-state electronic trip unit with adjustable LSIG functions. This provides comprehensive protection against long-time overloads, short-time delays, instantaneous short circuits, and ground faults.
What wire size range is supported by the SJD69400NGTH lugs?
When equipped with standard mechanical lugs, this JD-frame breaker accepts copper or aluminum conductors ranging from 3/0 AWG to 500 kcmil.
Can I swap the trip unit on the SJD69400NGTH to change its amperage?
No. The SJD69400NGTH is manufactured with a factory-sealed, non-interchangeable solid-state trip unit. To change the maximum frame rating, the entire breaker must be replaced.
Is the SJD69400NGTH rated for 100 percent continuous operation?
Yes, this breaker carries a 100 percent continuous current rating. When applying this rating, National Electrical Code requires the use of 90 degree Celsius copper wire sized to the 75 degree Celsius ampacity column, along with appropriately rated lugs.
How do I adjust the trip settings on the SJD69400NGTH?
The setting dials on the face of the Sensitrip electronic trip unit are rotary switches. When configuring the long-time, short-time, instantaneous, and ground fault parameters, ensure each dial is properly set to its mechanical detent (click stop) position.
