Product FAQs
5 answersWhich panelboards are compatible with the TK236150 breaker?
This K-frame breaker is designed for installation in GE A-Series panelboards, switchboards, and motor control centers.
What are the wire size requirements for the TK236150 lugs?
The included lugs accommodate copper or aluminum conductors ranging from 4 AWG to 300 kcmil. Always apply the manufacturer recommended torque during termination.
How is the trip unit configured on the TK236150?
It utilizes a thermal magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short circuit protection.
Why is the TK236150 branded as both ABB and General Electric?
ABB acquired GE Industrial Solutions. As a result, this legacy MCCB may feature either GE or ABB branding depending on the date of manufacture, but the form, fit, and function are identical.
What are the safety requirements for installing this bolt-on breaker?
Installation requires de-energizing the panelboard or switchboard. Ensure all power sources are disconnected, verify with a reliable voltage tester, and apply standard lockout procedures before bolting the breaker to the bus.
