Product FAQs
5 answersWhich panelboards and switchboards are compatible with the TJK436250 breaker?
This J-Frame breaker is designed for bolt-on installation in GE J600 panelboards, GE A-Series panelboards, and compatible GE switchboards.
What are the acceptable wire sizes for the lugs on the TJK436250?
The standard lugs accept either one wire ranging from 6 AWG to 600 kcmil or two wires ranging from 2/0 AWG to 250 kcmil. Both copper and aluminum conductors are supported.
Does the TJK436250 feature adjustable trip settings?
Yes, this breaker uses a thermal-magnetic trip unit with fixed thermal protection for long-time overloads and an adjustable magnetic setting for instantaneous short-circuit protection.
Why might the TJK436250 arrive with ABB branding instead of General Electric?
ABB acquired GE Industrial Solutions. As a result, newly manufactured TJK series breakers may feature ABB branding while retaining the exact same physical dimensions, mounting, and electrical characteristics as the legacy GE versions.
Can the TJK436250 be utilized in direct current systems?
Yes, this breaker is rated for DC applications up to 500VDC, providing a 20kA interrupting capacity at both 250VDC and 500VDC.
