Product FAQs
7 answersWhat enclosures and equipment accept the TB43200 circuit breaker?
This TB4 frame breaker is designed for bolt-on installation in GE Tri-Break panelboards, GE switchboards, and compatible motor control centers.
Why might the TB43200 feature ABB branding instead of General Electric?
Following the ABB acquisition of GE Industrial Solutions, these breakers may be manufactured with ABB labels. The form, fit, and function remain identical to the original GE specifications.
What applications require the 200kAIC rating of the TB43200?
The 200kAIC interrupting rating at 480V is designed for heavy industrial systems where extremely high fault currents are present. The Tri-Break design safely clears these massive faults to protect downstream equipment.
How does the adjustable magnetic trip function on this breaker?
The TB43200 features a thermal magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element. This allows electricians to dial in the instantaneous trip threshold to coordinate with motor inrush currents or other system requirements.
What does the LI trip function code indicate on the TB43200?
The LI designation means the breaker provides Long-Time and Instantaneous trip functions. The long-time function handles standard overloads, while the instantaneous function responds immediately to short circuits.
What are the lug wire size limits for the TB43200?
The terminals accept a single conductor from 6 AWG to 600 kcmil or dual conductors from 2/0 AWG to 250 kcmil. Both aluminum and copper wire are supported.
What are the primary safety checks before installing this bolt-on MCCB?
Verify that the panel is completely de-energized and locked out. Confirm that the system voltage does not exceed 600VAC and that the available fault current is within the 200kAIC limit before bolting the breaker to the bus.
