The Square D EGB Series is a standard thermal magnetic bolt-on breaker for commercial panelboards operating at 480Y/277V. The EGB34110 is commonly specified for feeder and branch circuit protection in office buildings, retail, healthcare facilities, and light industrial applications where 14kA IC is sufficient for the available fault current at the panelboard.
Typical Applications
- Commercial 3-phase panelboards at 480Y/277V
- Branch and feeder circuit protection in office buildings and retail facilities
- HVAC and mechanical equipment feeders
- Replacement for Square D EGB-frame 110A bolt-on breakers
Frequently Asked Questions
Q: What is the difference between the EGB34110 and EDB34110?
A: The EDB34110 has a higher interrupting capacity (18kA vs 14kA for the EGB34110). Specify the EDB when available fault current at the panel exceeds 14kA.
Q: What mounting type does the EGB34110 use?
A: The EGB34110 uses a Bolt-On mounting, compatible with Square D EGB-frame panelboards.
Q: Is the EGB34110 UL listed?
A: Yes, it is UL 489 listed and CSA C22.2 certified for North American electrical systems.
