Product FAQs
7 answersWhat equipment is the TB83800BK22 circuit breaker compatible with?
This 800A Tri-Break MCCB is designed for bolt-on installation in GE switchboards, motor control centers, and AV-Line switchboards.
Which lug terminal kit is compatible with the TB83800BK22 breaker?
The GE TCAL81 lug terminal kit is compatible with TB8 frame breakers. It accepts three aluminum or copper conductors sized from 3/0 AWG to 500 kcmil per phase.
What is the advantage of the Tri-Break technology used in the TB83800BK22?
The GE Tri-Break series utilizes an integrally fused design to provide advanced current-limiting capabilities. This allows the breaker to achieve a 200kAIC interrupt rating at 480VAC for superior system protection in heavy industrial environments.
How does the trip unit function on the TB83800BK22?
It features a thermal-magnetic trip unit with fixed thermal protection for long-time overloads and an adjustable magnetic setting for instantaneous short-circuit protection.
Will the TB83800BK22 breaker be branded as GE or ABB?
Following ABB acquiring GE Industrial Solutions, this breaker may feature either GE or ABB branding depending on the manufacturing date. The form, fit, function, and specifications remain identical regardless of the label.
What is the modern replacement series for the legacy GE TB8 frame?
For modern upgrades or panel retrofits, the legacy GE TB8 frame is typically replaced by the ABB Tmax XT series of molded case circuit breakers.
Does the TB83800BK22 provide current-limiting protection?
Yes, the integrally fused Tri-Break design provides advanced current-limiting protection, which restricts the let-through energy during a fault to protect downstream equipment and wiring.
