Product FAQs
6 answersWhat equipment is compatible with the JXD22B400 circuit breaker?
This 400A bolt-on breaker is designed to install directly into Siemens Sentron panelboards, SB switchboards, and compatible motor control centers.
What lug kit and wire sizes are used with the JXD22B400?
This breaker requires a separate lug kit, typically the TA2J6500. When equipped with these lugs, it accepts wire sizes from 3/0 AWG to 500 kcmil for copper, or 4/0 AWG to 500 kcmil for aluminum conductors.
How does the trip unit on the JXD22B400 function?
It uses a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit response. This allows you to coordinate the fault response with your specific system requirements.
Is the JXD22B400 rated for direct current (DC) systems?
Yes, in addition to its 240VAC rating, this 2-pole breaker is rated for 250VDC applications, providing a 30kA interrupting capacity for DC power distribution.
What frame family does the JXD22B400 belong to?
It is part of the legacy Siemens Sentron JD frame family. It shares the standard physical dimensions and mounting footprint of other 400A JD-frame molded case circuit breakers.
What is the modern replacement series for the JXD22B400?
The JXD22B400 is a legacy Sentron JD-frame breaker. While it is still used for direct replacements in existing infrastructure, Siemens has transitioned to the newer 3VA series for modern panelboard installations.
