Product FAQs
6 answersWhat equipment is the SEHA24AT0150 designed to fit?
This SE-frame breaker is designed for use in GE and ABB Spectra Series panelboards, switchboards, and motor control centers. It requires a bolt-on connection to the bus or mounting pan.
What adjustability does the LSI trip unit provide on this breaker?
The solid-state electronic trip unit features Long-Time, Short-Time, and Instantaneous (LSI) functions. This allows panel builders to fine-tune the trip curve for precise selective coordination with downstream devices.
Why is this breaker listed as both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, the SEHA24AT0150 may feature either GE or ABB branding, but the physical dimensions, mounting hardware, and electrical specifications remain identical.
What wire sizes are compatible with the standard lugs on this 150A breaker?
The standard factory lugs accept 12 AWG through 3/0 AWG wire. They are rated for both aluminum and copper conductors. Always verify the required torque specifications printed directly on the breaker faceplate during installation.
Can I use the SEHA24AT0150 in a 480V system with a high fault current?
This breaker has an interrupting capacity of 25kA at 480VAC. If your system's available fault current exceeds 25,000 amps at 480V, you will need to select a higher interrupting tier within the Spectra RMS family to safely clear the fault.
Does this breaker mount onto a standard DIN rail?
No. The SEHA24AT0150 is a unit-mount, bolt-on molded case circuit breaker. It must be bolted directly into compatible Spectra Series enclosures and is not designed for DIN rail applications.
