Siemens BQ2B03000S01 Two Pole Circuit Breaker

Siemens BQ2B03000S01 is a two‑pole molded‑case circuit breaker from the BQ family rated for 120/240 VAC with a nominal current of 30 A and a 10 kA interrupting rating, designed to protect branch circuits in commercial and industrial panels. The S01 suffix identifies a shunt‑trip variant that adds a 120 V shunt‑trip coil for remote tripping, while maintaining thermal‑magnetic protection and a common trip so both poles trip together on fault or overload. The unit supports load‑lug terminals and multiple mounting options (bolt‑on, lug‑in, or lug‑out configurations) for flexible installation, and its typical form factor measures about 6 in long by 4 in wide by 3 in high. This Siemens MCCB is built to safeguard 120/240 V circuits with reliable, coordinated protection and an optional remote‑trip capability when required.
