EH34100 - 100 Amp Circuit Breaker

When you’re maintaining or servicing an existing electrical system, finding the right breaker isn’t just about specs—it’s about getting a unit that fits properly and performs exactly as expected. The EH34100 3-pole 100 amp circuit breaker is designed for that purpose. Built for use in EH-4 frame panelboards, this plug-on thermal magnetic breaker provides dependable overcurrent protection while aligning with the physical and electrical requirements of legacy equipment. With its thermal magnetic trip design, the EH34100 responds to overloads through heat detection and reacts instantly to short circuits using magnetic protection. That balance helps keep your system protected without unnecessary interruptions. Its plug-on style makes installation straightforward, reducing downtime when replacing or maintaining existing breakers. Simply put, it’s a practical, no-nonsense solution built to do its job and keep systems running safely.
