EJB34035 - 35 Amp Circuit Breaker

EJB34035 - 35 Amp Circuit Breaker

When you need dependable circuit protection for a compatible Square D NF panelboard, the Square D EJB34035 is built to get the job done. This 35 Amp, 3-pole thermal-magnetic circuit breaker helps protect electrical systems from overloads and short circuits while delivering the consistent performance commercial and industrial facilities expect. Its bolt-on mounting design creates a secure connection within the panel, making it a practical choice for maintenance work, equipment upgrades, or replacing an existing breaker with a matching specification.

One feature electricians appreciate is the built-in trip indicator, which makes it easy to see when a breaker has tripped due to a fault. That saves valuable troubleshooting time and helps get equipment back online more quickly.
