Product FAQs
6 answersWhich enclosures and panelboards accept the TEF136030 circuit breaker?
This E-Frame breaker is designed for bolt-on installation in GE A-Series panelboards, GE switchboards, and motor control centers. It is commonly used for commercial power distribution and infrastructure upgrades.
How is the TEF136030 secured within a panelboard?
It utilizes a bolt-on mounting configuration, bolting directly to the busbar. This provides a secure, vibration-resistant connection that is ideal for heavy-duty commercial and industrial environments.
Why might my TEF136030 arrive with ABB branding instead of GE?
Following ABB's acquisition of GE Industrial Solutions, newer production runs of this legacy E-Frame breaker carry the ABB name. The physical dimensions, mounting hardware, and electrical specifications remain completely identical regardless of the label.
Can the thermal or magnetic trip points be adjusted on this breaker?
No, the TEF136030 features a non-interchangeable, fixed thermal-magnetic trip unit. The long-time and instantaneous (LI) protection parameters are factory set and cannot be modified in the field.
What frame size family does the TEF136030 belong to?
It is part of the legacy GE E-Frame family, specifically belonging to the E150 line of molded case circuit breakers which have a maximum frame rating of 150 amps.
Is the TEF136030 suitable for reverse feed applications?
Yes, this E-Frame breaker is capable of being reverse fed. This allows the line and load connections to be swapped if required by the specific panel or enclosure layout.
