Siemens Industry, Inc. B380H Three-Phase Circuit Breaker

Siemens B380H is a three‑pole molded‑case circuit breaker (MCCB) from the BLH family, rated for 80 A at 240 V AC with a 22 kA interrupting rating, designed for bolt‑on mounting in panelboards and feeders in commercial and industrial electrical installations. It uses a thermal/magnetic trip unit and provides common‑trip protection for all three poles; variants in the BLH line are commonly specified for 120/240 V applications, but this unit is specified for 240 V nominal, with panelboard mounting and UL 489/CSA alignment. With a 3‑pole configuration, bolt‑on mounting, and molded‑case construction, the B380H is intended for three‑phase distribution circuits where reliable protection and coordination are required in panelboard protection systems.
