E41B070 - 70Amp Circuit Breaker

E41B070 - 70Amp Circuit Breaker

The E41B070 is a 70 Amp single-pole molded case circuit breaker commonly used in commercial and industrial electrical systems where maintaining the original breaker specifications is important. When an existing E41-series breaker reaches the point where replacement is needed, this model provides the same pole configuration, amperage rating, and bolt-on mounting style to help keep the installation consistent with its original design.

You'll often find breakers like the E41B070 protecting lighting circuits, HVAC equipment, distribution panels, and other dedicated electrical loads. Because it features a bolt-on connection, it installs securely in compatible equipment and is frequently chosen for maintenance projects, equipment repairs, and panel refurbishments where matching the existing setup matters just as much as the electrical rating itself.

Whether you're servicing an existing panelboard, replacing a failed breaker, or maintaining facility electrical equipment, the E41B070 is often selected because it delivers the form, fit, and function needed to keep the system operating as originally designed.
