Siemens AG BQD6230 Molded Case Circuit Breaker

Siemens BQD6230 is a 2‑pole molded‑case circuit breaker (Type BQD6) designed to protect circuits in low‑voltage distribution panels. Rated 30 A, it is suitable for systems up to 600 V AC (commonly listed as 347/600 VAC), and carries a 10 kA short‑circuit interrupting rating at 600 V, providing reliable protection for feeders and motor circuits in commercial and light industrial setups. This bolt‑on version integrates with Siemens MCCB enclosures and uses a thermal‑magnetic trip unit to coordinate protection against overloads and short circuits. The device is listed for North American use, with CSA certification, and is often specified for Canadian applications as well as US installations. In typical installations, its 2‑pole configuration helps secure both hot conductors simultaneously, ensuring trip coordination with other breakers in the same panel. The continuous current rating at 40°C is 30 A, aligning with the nominal 30 A rating and supporting stable operation in standard panel environments. Verified part numbers and catalogs identify the BQD6230 as part of Siemens’ BQD6 family, offering a compact bolt‑on form factor suitable for retrofit or new builds in industrial and commercial distributions.
