Description
Built for heavy-duty industrial applications, the GE TB12030 is a 30A, 2-pole current-limiting circuit breaker. It utilizes thermal-magnetic trip technology to deliver reliable overcurrent and short-circuit protection. Designed for unit-mount configurations, this device integrates into GE switchboards, motor control centers, and A-Series panelboards. Factory-installed line and load lugs ensure a secure connection. The TB1 frame features internal fusing to achieve a 200kAIC rating at 480VAC.Specifications

Product FAQs
5 answersWhich panelboards and enclosures are compatible with the TB12030 circuit breaker?
This Tri-Break series breaker is designed for use in GE A-Series panelboards, GE switchboards, and motor control centers. Always verify fitment with your specific enclosure model before installation.
What wire sizes are accepted by the lugs on the TB12030?
The line and load side lugs accept wire gauges from 14 AWG up to 1/0 AWG. The terminals are rated for both copper (Cu) and aluminum (Al) conductors.
How does the current limiting feature of the TB12030 operate?
As a current limiting breaker, it is designed to clear a fault in less than half a cycle. This rapid response reduces the let-through energy during a short circuit, providing enhanced protection for downstream equipment.
How is the TB12030 breaker mounted in an enclosure?
This is a unit mount, feed-thru circuit breaker. It bolts directly to the mounting surface or backpan rather than plugging into a busbar, requiring appropriate fasteners for a secure installation.
What does the LI trip function indicate on this breaker?
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.
