Brand New Siemens E42B030 – 30A 2 Pole Molded Case Circuit Breaker

Engineered for commercial and industrial applications, the Siemens E42B030 is a 2-pole, 30A molded case circuit breaker from the legacy E4 frame family. It provides thermal-magnetic trip protection with a 65kAIC rating at 240VAC and 18kAIC at 480VAC. This bolt-on unit mounts into classic Siemens or ITE Sentron panelboards, switchboards, and motor control centers. As a discontinued model, it is commonly replaced by the modern ED42B030 (ED4 frame) for system upgrades.
