Description
Designed for commercial electrical systems, the GE EZSEDA36AT0150 is a 3-pole, 150A molded case circuit breaker. It utilizes a solid-state trip system to provide highly accurate overcurrent protection. This unit-mount breaker installs into GE Spectra Series panelboards and switchboards. For future upgrades, it is replaced by the ABB Tmax XT4 series using a retrofit kit. Rated 18 kAIC at 480V, the SE-frame breaker features true RMS sensing and adjustable LSI trip functions.Specifications

Product FAQs
7 answersDoes the EZSEDA36AT0150 require a rating plug to operate?
Yes, GE Spectra RMS SE150 frame breakers require a front-mounted, field-installable rating plug, such as the SRPE150A150, to establish the continuous ampere rating. The breaker will not function properly without a rating plug installed.
Which lug terminals are compatible with this SE150 frame breaker?
This breaker is compatible with TCAL18 lug terminals, which accommodate the 12 to 3/0 AWG aluminum or copper wire range specified for this unit. Lugs are typically sold separately and must be installed in the field.
What protection features are included in the LSI electronic trip unit?
The LSI designation indicates that the solid-state trip unit provides Long-Time (overload), Short-Time (short-circuit with delay), and Instantaneous (immediate short-circuit) protection functions. The short-time and instantaneous settings can be adjusted to coordinate with other protective devices.
Can the continuous current rating of this breaker be lowered in the field?
Yes, the continuous ampere rating can be reduced below the 150A frame maximum by installing a lower-amperage SRPE rating plug designed for the SE150 frame, without needing to replace the entire circuit breaker.
What must be verified before changing the rating plug on this breaker?
Since the installed rating plug establishes the ampere rating of the breaker, the installer must verify that the connected cable and bus bar ampacity meet National Electrical Code (NEC) requirements for the new rating.
Is the GE Spectra RMS series still in active production?
No, following ABB's acquisition of GE Industrial Solutions, the Spectra RMS series has been phased out. ABB has replaced this legacy line with the Tmax XT series of molded case circuit breakers.
How can I upgrade an existing Spectra panelboard if the EZSEDA36AT0150 is unavailable?
ABB manufactures Tmax XT retrofit kits designed specifically for legacy GE Spectra panelboards and switchboards. These kits allow you to install modern Tmax XT breakers into existing Spectra plug-in or bolt-on modules while maintaining the original UL listing.
