EHB3050L - 50Amp Circuit Breaker

EHB3050L - 50Amp Circuit Breaker

When a circuit breaker needs to be replaced, getting the right match is one of the most important parts of the job. The EHB3050L is a 3-pole, 50-amp Type EHB thermal-magnetic circuit breaker made for compatible pre-1989 panelboards, giving maintenance professionals a replacement that matches the original equipment's design and electrical ratings. Instead of changing the existing setup, you can maintain the intended configuration of the system with a breaker built for the same application.

Built to last, the EHB3050L is a dependable choice for facilities that continue to operate legacy electrical distribution systems and need a replacement that matches the original specifications.

Where It Works Best

The EHB3050L is commonly used anywhere compatible Type EHB panelboards remain in service. You'll often find these breakers in manufacturing facilities, warehouses, schools, office buildings, healthcare facilities, and other commercial or industrial properties with legacy electrical distribution equipment. When the original installation specifies a 3-pole, 50-amp Type EHB circuit breaker, using a replacement with matching electrical ratings and physical dimensions helps preserve the original design of the system without requiring changes to the existing panel.
