Part of the legacy E-Frame family, the GE TEL136040 is a 3-pole, 40A molded case circuit breaker designed for commercial and industrial power distribution. This unit-mount breaker installs into GE A-Series panelboards, Spectra switchboards, and motor control centers. It serves as a higher-interrupting substitute for TED136040 and THED136040 breakers. Featuring a current-limiting design, it delivers a 65 kAIC rating at 480VAC to minimize let-through energy and protect downstream equipment.

What equipment is the TEL136040 designed to fit?
This E-frame breaker is designed for use with GE A-Series panelboards, GE Spectra switchboards, and compatible motor control centers.
What wire sizes are accepted by the load side lugs on this breaker?
The terminals accommodate 14 to 3 AWG copper wire or 12 to 1 AWG aluminum wire. Ensure proper torque specifications are followed during installation.
What does the LI trip function indicate on the TEL136040?
The LI designation means the thermal-magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection. Both the thermal and magnetic trip points are fixed and non-interchangeable.
How is this breaker installed into an electrical system?
This is a unit-mount, bolt-on circuit breaker. It bolts directly to the bus or mounting pan rather than snapping into place, providing a secure mechanical and electrical connection for commercial applications.
Is the TEL136040 a current-limiting circuit breaker?
Yes, the TEL series operates as a current-limiting molded case circuit breaker. This design helps reduce the let-through energy during a fault, offering enhanced protection for downstream equipment.
