EB3100 - 100Amp Circuit Breaker

EB3100 - 100Amp Circuit Breaker

When you're maintaining an older electrical distribution system, finding the right replacement breaker is often more important than finding the newest one. The EB3100 100 Amp 3-Pole Type EB Circuit Breaker was designed for use in compatible Type EB panelboards manufactured before 1989, making it a practical choice for keeping existing equipment operating as intended.

Built with a thermal-magnetic trip mechanism, the EB3100 helps protect electrical systems from both overload conditions and short circuits. Its 100-amp capacity and 3-pole design make it suitable for a wide range of three-phase power distribution applications found in commercial buildings, industrial facilities, schools, healthcare campuses, and other properties that continue to rely on legacy electrical infrastructure.

One of the key advantages of the EB3100 is its compatibility with existing Type EB installations. Rather than requiring modifications to approved equipment, this breaker is designed to provide the form, fit, and function needed for servicing compatible panelboards.
