Product FAQs
6 answersWhich Square D panelboards are compatible with the RGA36120CU44ALV circuit breaker?
This 1200A R-frame breaker is designed for use in Square D I-Line power distribution panelboards and switchboards. It requires a bus structure rated to accommodate R-frame breakers, such as the HCR-U series.
What does the U44A in the RGA36120CU44ALV catalog number indicate?
The U44A suffix signifies that the breaker is equipped with a MicroLogic 6.0A (Ammeter) electronic trip unit. This provides adjustable Long-Time, Short-Time, Instantaneous, and Ground-Fault (LSIG) protection, along with integrated current metering capabilities.
Is the RGA36120CU44ALV rated for 100% continuous current?
Yes, the C in the catalog number indicates that this breaker is 100% rated. It can carry its full 1200A continuous current rating without the standard 80% derating, provided it is installed in a properly sized enclosure with appropriately rated conductors.
How many conductors per phase can the RGA36120CU44ALV lugs accept?
The factory-installed mechanical lugs are designed to accept four conductors per phase. They accommodate wire sizes from 3/0 AWG up to 600 kcmil for both aluminum and copper wire.
How does the RGA36120CU44ALV connect to the panelboard bus?
It utilizes the Square D I-Line plug-on mounting system. The line side features plug-on jaws that connect directly to the panelboard bus stack, while the load side uses mechanical lugs for wire termination.
What protection functions are included with the MicroLogic 6.0A trip unit?
The MicroLogic 6.0A provides fully adjustable LSIG protection. This allows you to set the pickup and delay parameters for Long-Time, Short-Time, Instantaneous, and Ground-Fault conditions to ensure proper system coordination.
