Product FAQs
6 answersWhich panelboards are compatible with the TEF134070 circuit breaker?
This legacy E-Frame breaker is designed to bolt directly into GE A-Series panelboards, GE switchboards, and motor control centers.
What is the direct replacement for the legacy TEF134070?
The TEF134070 has been officially superseded by the TED134070. The TED series serves as the modern upgrade and maintains compatibility with the same enclosures.
Why is the TEF134070 listed under both the ABB and General Electric brands?
ABB acquired the GE Industrial Solutions low-voltage business. Legacy GE circuit breakers, including the E-Frame series, are now managed under the ABB brand portfolio while retaining their original design and compatibility.
What are the acceptable wire gauges for the TEF134070 lugs?
The standard lugs accommodate 3 AWG to 3/0 AWG copper conductors, and 1 AWG to 3/0 AWG aluminum conductors.
Are the thermal and magnetic trip points adjustable on this breaker?
No, the TEF134070 is equipped with a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous protection settings are factory set and cannot be modified in the field.
How does the thermal-magnetic trip unit operate on the TEF134070?
It utilizes a bimetallic element to provide long-time delay protection against overloads, combined with a magnetic armature for instantaneous response to short circuits.
