FAQs
The LGE3400FAGC uses metric mounting hardware designed to fit standard control panels. Start by verifying panel clearance for a three-pole LG-frame MCCB, ensure the bus bars and wiring clearances meet NEC/IEC guidelines, then mount using the supplied metric hardware. Tighten line and load connections to the manufacturer’s torque specifications and perform a functional test before energizing the circuit.
The breaker provides 65 kAIC at 240 VAC, 35 kAIC at 480 VAC, and 18 kAIC at 600 VAC. This range supports high fault-current conditions in typical industrial installations while enabling selective coordination with downstream protection to minimize unplanned downtime and equipment damage.
Yes. The LGE3400FAGC is rated for 50 to 60 Hz operation, making it suitable for global production facilities and control panels that require consistent protection across varying frequency environments. The 400 A rating and 100% rated performance further ensure reliable operation in diverse loads and startup transients.
This breaker is CE marked and UL Listed, with CSA certification and IEC rating, supporting international compliance. The catalog notes also indicate HACR rating, which is important for HVAC-related protection. These certifications help ensure safety, reliability, and regulatory alignment in multinational installations.
