Siemens CF3-B030U is a three-pole molded case circuit breaker (MCCB) rated 30 A at 600 V, designed to protect electrical circuits from overcurrent. It traces its lineage to the ITE CF3 family and represents Siemens' continuation of that line for low‑voltage distribution and machine-control applications. This 3P MCCB provides dependable overcurrent protection for multi‑phase circuits up to 600 V in industrial and commercial electrical systems.
