Square D - EDB34110 – 110A 3-Pole 480V High IC Bolt-On Circuit Breaker 18kA
Square D - EDB34110 – 110A 3-Pole 480V High IC Bolt-On Circuit Breaker 18kA
Product images are representative only. Actual product may vary.
The Square D EDB34110 is a 3-pole, 110-amp thermal magnetic molded case circuit breaker rated for 480Y/277VAC with a High IC rating of 18kA. Its Bolt-On mounting makes it ideal for commercial and industrial panelboards operating at 480V where higher available fault currents demand greater interrupting capacity than the standard EGB frame provides.

Features & Benefits
- 18kA High IC interrupting capacity — handles higher available fault currents than the standard EGB frame at 480V
- Thermal magnetic trip — accurate overload and short-circuit protection without nuisance trips
- Bolt-On mounting — secure, vibration-resistant installation in Square D EDB-compatible panelboards
- UL 489 listed and CSA C22.2 certified for full North American code compliance
- 480Y/277V rating covers the full range of 3-phase commercial and industrial distribution
The Square D EDB High IC Series is specified when short-circuit calculations show available fault current exceeding the 14kA rating of the standard EGB frame. Common in commercial buildings served from larger utility transformers, the EDB34110 provides the extra interrupting margin required by the NEC and IEEE 1584 arc flash standards without requiring a larger frame size.
Typical Applications
- Commercial 3-phase panelboards at 480Y/277V with higher fault current exposure
- Industrial feeder and branch circuit protection
- Healthcare, data centers, and facilities with large utility service
- Direct replacement for Square D EDB-frame 110A bolt-on breakers
Frequently Asked Questions
Q: What is the difference between the EDB34110 and EGB34110?
A: The EDB34110 has a higher interrupting capacity — 18kA vs 14kA for the EGB34110. Specify the EDB when available fault current at the panel location exceeds 14kA.
Q: What mounting type does the EDB34110 use?
A: The EDB34110 uses a Bolt-On mounting configuration, compatible with Square D EDB-frame panelboards.
Q: Is the EDB34110 UL listed?
A: Yes, it is UL 489 listed and CSA C22.2 certified for use in North American electrical systems.
