Product FAQs

6 answers
Is the SGLA36AT0400 a complete breaker ready for wiring?

No, the SGLA36AT0400 is a frame only. To complete the breaker for installation, you must separately source and install an interchangeable rating plug, line and load lugs, and mounting hardware.

Which rating plugs are compatible with the SGLA36AT0400 frame?

This 400A SG-frame breaker accepts GE SRPG400 series rating plugs. You can use the SRPG400A400 for a full 400-amp rating, or install lower amperage plugs like the SRPG400A300 or SRPG400A225 to establish a lower trip point for your system.

Which lug kit is designed for this 3-pole SG frame?

The TCLK365 3-pole lug kit is typically used for this frame. It accepts either one 8 AWG to 600 kcmil conductor or two 2/0 AWG to 500 kcmil conductors per phase, supporting both copper and aluminum wire.

What adjustments does the LSI trip unit provide?

The electronic LSI unit provides adjustable Long-Time, Short-Time, and Instantaneous trip functions. This solid-state true RMS sensing allows panel builders and electricians to achieve precise selective coordination with upstream and downstream devices.

Can this breaker be used in standard commercial load centers?

No. The SGLA36AT0400 features a bolt-on mounting style specifically engineered for high-capacity industrial applications, including GE and ABB Spectra Series panelboards, switchboards, and motor control centers.

Are GE Spectra RMS breakers now manufactured by ABB?

Yes. Following ABB's acquisition of GE Industrial Solutions, the Spectra RMS line is an ABB platform. You may find the SGLA36AT0400 breaker and its required accessories branded under either the GE or ABB name, but they are fully interchangeable.
