FAQs

Install the LGS3300FAG by mounting the unit in the panel using metric hardware designed for LG-frame MCCBs. Connect line and load terminals per the wiring diagram, ensure secure torque on all connections, and verify 50/60 Hz compatibility. Confirm proper three-pole alignment and trip setting (T185) before energizing the system to ensure reliable protection and proper coordination with upstream devices.
Key performance ratings include a 300 A amperage rating, 85 kAIC at 240 Vac, 50 kAIC at 480 Vac, and 25 kAIC at 600 Vac. It operates at 50/60 Hz, is HACR-rated, and uses fixed thermal with adjustable magnetic trip (T185). These ratings support safe operation of motors and heavy loads while meeting common global protection standards.
Yes. The LG-frame Series G complete breaker is designed for motor protection within distribution panels and machine control centers. The adjustable magnetic trip and high interrupt ratings provide selective coordination for motor feeders, reducing nuisance trips while protecting start-up surges and fault currents inherent to motors in manufacturing environments.
