Part of the Tri-Break family, the GE TB13040 is a 3-pole, 40A current limiting MCCB. It features an integrally fused design to restrict let-through energy, protecting downstream equipment from severe faults. This unit-mount breaker integrates seamlessly into GE switchboards, motor control centers, and A-Series panelboards. It includes standard line and load lugs for feed-thru connections. Delivering 200kAIC at 480VAC, it utilizes fixed thermal-magnetic technology for reliable LI protection.

Product FAQs
5 answers
Which panelboards and enclosures are compatible with the TB13040 circuit breaker?
This unit mount breaker is designed for installation in GE switchboards, motor control centers, and GE A-Series panelboards. Verify your specific enclosure accepts TB1 frame current limiting breakers before installation.
How does the current limiting feature of the TB13040 benefit a power distribution system?
As a current limiting breaker, it interrupts short circuits extremely fast, reducing the let-through peak current and energy. This protects downstream components and often allows for series rating with lower rated downstream breakers, which can reduce overall system costs.
Is there a difference between the GE TB13040 and the ABB TB13040?
No. ABB acquired GE Industrial Solutions in 2018. The TB13040 is the exact same Tri-Break molded case circuit breaker, manufactured to the same specifications, regardless of whether it carries the GE or ABB brand name.
What type of conductors can be used with the standard lugs on this breaker?
The factory installed lugs accept both copper and aluminum conductors ranging from 14 AWG to 1/0 AWG. Always apply the correct torque specifications listed on the breaker faceplate to ensure a secure connection.
Can this breaker be used in direct current applications?
Yes, the TB13040 is rated for DC applications up to 250 VDC with an interrupting capacity of 10kA. Ensure your specific DC system design aligns with standard thermal magnetic trip characteristics.
