Description
Built for industrial power systems, this 3-pole, 600A GE molded case circuit breaker provides reliable long-time and instantaneous (LI) trip functions. Designed with a bolt-on mounting style, it secures into GE switchboards and AV-Line panels. This TB8 frame can be substituted with the Tmax XT series via a retrofit. With a 200 kAIC rating at 480VAC, it incorporates current-limiting capabilities to quickly clear faults and protect downstream equipment.Specifications

Product FAQs
7 answersWhat enclosures and panels are compatible with the TB836T600?
This breaker is designed for use in GE switchboards, motor control centers, and AV-Line switchboards. When installing in GE CCB, QMR, AV1, or AV2 panelboards, the TB8SPK single-branch mounting hardware kit is required.
Are line and load lugs included with the TB836T600?
No, GE TB8 frame circuit breakers are factory assembled without line or load lugs. Compatible lug kits, such as the TCALK3812 which accepts three 3/0 to 500 kcmil Cu/Al wires per phase, must be sourced separately.
Is the trip unit on the TB836T600 adjustable?
Yes, it features an interchangeable thermal-magnetic trip unit with fixed thermal (long-time) protection and an adjustable magnetic (instantaneous) trip, allowing you to fine-tune the short-circuit response.
How does the TB836T600 achieve a 200kA interrupting rating at 480V?
As part of the GE Tri-Break series, this breaker is integrally fused. It utilizes built-in current limiters to safely interrupt extremely high fault currents up to 200kA at 480VAC and 100kA at 600VAC.
What frame size is the TB836T600?
It belongs to the GE TB8 frame group, which accommodates amperages from 600A up to 800A.
Can the trip unit on the TB836T600 be swapped for a different amperage?
Yes, the TB836T600 features an interchangeable trip unit design. This allows the 600A trip unit to be removed and replaced with another compatible TB8 trip unit if load requirements change, without replacing the entire breaker frame.
What safety precautions should be taken before adjusting the magnetic trip settings?
Always ensure the breaker is de-energized and properly locked out or tagged out (LOTO) before making any adjustments to the instantaneous trip dials. Adjustments should only be performed by a qualified electrician in accordance with a coordination study.
