ED43B080 - 80Amp Circuit Breaker

ED43B080 - 80Amp Circuit Breaker

When you need a compatible replacement circuit breaker to help maintain the operation of an existing electrical distribution system, the Siemens ED43B080 provides the ratings and configuration required for many commercial and industrial applications. This 80 Amp, 3-pole molded case circuit breaker is designed for 480V AC electrical systems and features a thermal-magnetic trip unit that helps protect circuits from both overloads and short circuits.

Rated at 18kA interrupting capacity (18kAIC) at 480V AC, the Siemens ED43B080 is suitable for applications that require this fault-current rating. The breaker is equipped with factory-installed load-side lugs (LN1E100) that accept 10 AWG through 1/0 AWG copper or aluminum conductors, providing compatibility with a wide range of existing wiring configurations.
