Product FAQs
10 answersDoes this 400A frame breaker come with a rating plug?
Yes, this specific SGLC3404L4XX configuration includes a GTP0225U0306 rating plug, which sets the maximum continuous current to 225A. The SG frame utilizes interchangeable rating plugs, allowing you to adjust the breaker rating without replacing the entire unit.
What does the LSIG designation mean for the SGLC3404L4XX?
LSIG indicates that the integrated microEntelliGuard electronic trip unit provides adjustable protection parameters for Long-Time, Short-Time, Instantaneous, and Ground-Fault conditions. This allows for precise coordination in complex distribution systems.
Are terminal lugs included with this breaker?
No, lugs are not included. You will need to source compatible SG frame lug kits separately. The breaker accepts wire sizes from 8 AWG up to 600 kcmil for both copper and aluminum conductors.
Can the SGLC3404L4XX be reverse fed?
Yes, this breaker is reverse feed capable. This allows line connections to be made at either the top or bottom terminals, providing flexibility for panelboard and switchboard wiring.
What field accessories can be added to this SG frame breaker?
The SGLC3404L4XX supports a range of field installable accessories, including shunt trips, auxiliary switches, undervoltage releases, motor operators, and padlock attachments.
Is the SGLC3404L4XX the most current model for new panel builds?
While this breaker is the exact replacement for existing GE Spectra Series panelboards, switchboards, and motor control centers, it has been superseded by the ABB Tmax XT5 series for completely new installations.
Is this circuit breaker suitable for HVAC equipment?
Yes, the SGLC3404L4XX is HACR rated, making it approved for use with heating, air conditioning, and refrigeration equipment.
Does this breaker feature True RMS sensing?
Yes, the electronic trip unit utilizes True RMS sensing. This ensures accurate overcurrent protection even in environments with high harmonic distortion from non-linear loads like variable frequency drives.
Is the SGLC3404L4XX a 100% rated breaker?
Yes, this model is 100% rated. It can carry its full continuous current rating continuously without the standard 80% derating, provided it is installed in an enclosure approved for 100% rated applications.
Is the SGLC3404L4XX a current limiting circuit breaker?
Yes, this SG frame breaker features a current limiting design. It rapidly interrupts high fault currents to reduce let-through energy and protect downstream equipment.
