🔹 Application
The LGH3630NN is intended for high-current electrical distribution and circuit-protection applications using the Eaton Series G LG-frame architecture. Its three-pole, 630 A configuration makes it applicable to industrial switchgear, distribution equipment, motor-control installations, and other high-current systems where the matching Eaton breaker configuration is required.
Eaton lists the unit as UL Listed, CSA Certified, IEC Rated, and CE Marked. The official catalog also notes that the LG breaker is HACR rated.
🔹 Replacement Notes
Before ordering or installing an LGH3630NN, verify:
- Exact catalog number: LGH3630NN
- Three-pole configuration
- 630 A frame rating
- Required system voltage
- Trip-unit type and rating
- Line/load terminals
- Mounting and operating accessories
- Existing Eaton Series G configuration
Important: LGH3630NN should not automatically be treated as a complete ready-to-install breaker because Eaton’s catalog identifies this catalog number as frame only. The actual item should be checked for its installed trip unit and accessories.
