Description
Built for circuit protection, the General Electric TEF124015 molded case circuit breaker is rated 15A and has 2 poles. It belongs to the TEF series and uses bolt-on mounting. Its thermal magnetic trip responds to overloads and short circuits. The LI trip function provides long-time and instantaneous protection, interrupting the circuit when these fault conditions occur.Specifications

Product FAQs
8 answersHow do I select the General Electric TEF124015 by current rating?
Its 15A rating is the nominal current rating used for circuit sizing, not an instantaneous trip threshold. Select it when the circuit design requires 15A overcurrent protection.
What AC and DC voltages is this breaker rated for?
The voltage ratings are 240VAC, 480VAC and 250VDC. Match both the circuit voltage and whether the circuit is AC or DC when selecting the breaker.
How do I check whether its interrupting rating is adequate at 480V?
The interrupting rating is 14kAIC at 480V. Compare that rating with the available fault current at the installation point; the available fault current must not exceed the breaker's interrupting rating.
How does the trip operate, and can I adjust it?
The thermal-magnetic LI trip provides long-time overload and instantaneous short-circuit protection. Thermal operation responds to sustained overloads, while magnetic operation responds rapidly to high fault currents. Both functions are fixed, so selection must suit the circuit without field adjustment of trip settings.
What do the pole count and phase rating mean for circuit selection?
This is a 2-pole, single-phase breaker. Use those characteristics when selecting protection for a single-phase circuit requiring two protected circuit conductors.
Does this breaker use bolt-on or plug-in mounting?
It uses bolt-on mounting, with a mechanically fastened connection rather than plug-in attachment. Plan installation access for securing the bolted connection.
What conductor sizes can I terminate, and what connection type does it use?
The lug terminals accept conductors from 14 AWG through 8 AWG. Keep conductor selection within that range while also meeting the circuit's ampacity requirements.
What dimensions should I use when planning installation space?
The E-Frame breaker measures 6.31 in high, 3.38 in deep and 2.75 in wide. Use these dimensions to plan the space occupied by the breaker.
