ED43B070 - 70Amp Circuit Breaker Description
ED43B070 - 70Amp Circuit Breaker
When you're replacing an existing molded case circuit breaker, having the correct match helps keep your electrical system operating as originally designed. The Siemens ED43B070 is a 70 Amp, 3-pole molded case circuit breaker from the trusted Sentron ED frame family, built for use in 480V AC electrical distribution systems. Designed as a form, fit, and functional replacement for compatible Siemens installations, this breaker is well suited for maintenance, repairs, and equipment servicing in commercial and industrial environments.
The ED43B070 features a thermal-magnetic trip unit that responds to both sustained overloads and short-circuit conditions, helping protect electrical equipment and branch circuits from damage. With an 18kA interrupting capacity (18kAIC) at 480V AC, it is intended for applications that require the electrical ratings and physical dimensions of the original Siemens ED frame breaker.
