Product FAQs
6 answersWhich panelboards accept the TLB134030 circuit breaker?
It is designed for installation in General Electric panelboards configured to accept bolt-on TB frame or TLB1 frame molded case circuit breakers.
What are the wire gauge requirements for the terminal lugs on this breaker?
The terminal lugs accept copper or aluminum conductors ranging from 14 AWG to 1/0 AWG. Ensure proper torque specifications are followed during installation.
How does the LI trip function operate on the TLB134030?
The LI designation indicates a thermal magnetic trip unit. The thermal element provides Long-Time protection against sustained overloads, while the magnetic element provides Instantaneous protection against short circuits.
Are the thermal or magnetic trip settings adjustable on this breaker?
No, this breaker features a fixed thermal and fixed magnetic trip unit. Neither the overload nor the short circuit trip points can be adjusted in the field.
Can this breaker be used in systems requiring a 65kAIC rating?
Yes, but only on 240VAC systems. If applied on a 480VAC system, the maximum interrupting capacity is limited to 50kAIC.
Will I receive an ABB or General Electric branded breaker when ordering the TLB134030?
Because ABB acquired GE Industrial Solutions, this exact component may ship with either ABB or General Electric branding. The physical dimensions, mounting, and electrical specifications are identical regardless of the label.
