Product FAQs
7 answersWhat panelboards are compatible with the EZSKHA36AT0800 circuit breaker?
This breaker is specifically designed for use in GE EntellEon power panelboards. The EZ prefix in the catalog number indicates it is configured as a branch breaker kit for these specific panels.
Does this breaker require a separate rating plug?
Yes, GE Spectra RMS SK frame breakers require a compatible SRPK rating plug to establish the continuous current rating. The plug must be sized at or below the 800A maximum sensor rating of this frame.
Does this breaker feature a plug-on or bolt-on connection?
While the base SK frame breaker utilizes a bolt-on connection, the EZSKHA36AT0800 kit includes the necessary base components to convert it to a plug-on module specifically for GE EntellEon panelboards.
What adjustments can be made on the electronic trip unit?
The solid-state electronic trip unit features LSI functions, allowing you to adjust the Long-Time, Short-Time, and Instantaneous trip settings to coordinate with your specific electrical system requirements.
What size wire can be used with the included lugs?
The factory lugs accept three 3/0 AWG to 500 kcmil aluminum or copper conductors per phase. Ensure all connections are torqued to the manufacturer specifications printed on the breaker label.
What is the difference between the EZSKHA36AT0800 and a standard SKHA36AT0800?
The standard SKHA36AT0800 is a traditional molded case circuit breaker. The EZSKHA36AT0800 kit includes that base breaker along with the specialized plug-in base and hardware required for mounting in a GE EntellEon panelboard.
What safety precautions should be taken before adjusting the LSI trip settings?
Always de-energize the panelboard before modifying the Long-Time, Short-Time, or Instantaneous settings. Adjustments should only be performed by a qualified electrician in accordance with a properly engineered coordination study.
