EB3030L - 30Amp Circuit Breaker

EB3030L - 30Amp Circuit Breaker

Keeping an older electrical system operating safely often comes down to finding the right replacement components. The EB3030L Type EB Circuit Breaker is designed for facilities that continue to rely on compatible Type EB panelboards manufactured before 1989, providing the form, fit, and function needed to match the original system design. Whether you're replacing a damaged breaker during maintenance, troubleshooting a circuit issue, or stocking critical spare parts, the EB3030L helps support the continued operation of existing electrical infrastructure.

For maintenance professionals, electricians, and facility managers, compatibility is often just as important as electrical ratings. That's why the EB3030L was designed specifically for use in older Type EB panelboards. Rated 10kA A.I.C. at 240VAC and suitable for operation in ambient temperatures up to 40°C (104°F), this breaker delivers the characteristics required for legacy systems that remain in service today. Built to last, it provides a practical replacement solution for commercial, industrial, institutional, and municipal facilities that depend on established electrical distribution equipment.
