Description
Delivering massive 800-amp capacity, this integrally fused three-pole breaker achieves a 200kAIC interrupt rating at 480VAC. The TB83800 is engineered for robust industrial power distribution, mounting securely into GE AV-Line switchboards and motor control centers. While this specific Tri-Break frame has been succeeded by the ABB Tmax XT series for new installations, it remains a critical exact-fit replacement component for maintaining existing high-fault commercial electrical infrastructure.Specifications

Product FAQs
6 answersWhat types of enclosures and panels is the TB83800 compatible with?
This Tri-Break MCCB is designed to mount securely into GE AV-Line switchboards, standard GE switchboards, and motor control centers.
Is the GE TB83800 still manufactured for new installations?
The legacy TB8 Tri-Break frame has been succeeded by the ABB Tmax XT series for new designs. However, the TB83800 remains available as an exact-fit replacement component for maintaining existing high-fault commercial electrical infrastructure.
What mounting hardware kit is required to install this breaker in CCB or QMR panels?
You will need the GE TB8SPK mounting hardware kit, which provides the necessary copper straps and hardware for a single-branch mounting configuration.
Which lug terminal kit is compatible with the TB83800?
The GE TCAL81 lug kit is compatible with the TB8 frame. It accommodates three conductors sized from 3/0 AWG to 500 kcmil, accepting either copper or aluminum wire.
How does this breaker achieve a 200kAIC interrupt rating at 480V?
The TB83800 utilizes an integrally fused design with built-in current limiters. This provides advanced current-limiting capabilities to safely interrupt massive high-fault currents in demanding commercial environments.
Are the trip settings on the TB83800 adjustable?
It features an interchangeable thermal-magnetic trip unit with LI functions. The long-time thermal protection is fixed at 800A, while the instantaneous magnetic trip function is adjustable to coordinate with your specific system requirements.
