The BQD330 is a Siemens 3P30A bolt-on circuit breaker, designed for 480V applications. With a robust interrupting capacity of 14kA, this breaker ensures reliable performance and maximum safety in various industrial settings. Perfect for protecting your electrical equipment and circuits, it offers both durability and efficiency for your operational needs.
The BQD330 is a bolt-on breaker from Siemens' BQD frame series, intended for Siemens/ITE commercial and industrial panelboards designed to accept BQD-series bolt-on breakers. It is not designed for residential loadcentres or plug-in panel applications. Because compatibility depends on your specific panelboard model and bus configuration, we recommend sending us your panel details so we can confirm a proper fit before ordering.
The Siemens BQD series is considered a hard-to-find product line. Northern Breaker Group specializes in sourcing obsolete and discontinued breakers, including BQD-frame units. Whether new old-stock or thoroughly tested surplus, we can often source the BQD330 when standard supply channels cannot.

Yes — a breaker rated for 480V is generally suitable for use at lower voltages such as 208V or 240V, provided all other specifications (pole count, amperage, bolt-on mounting, and panel compatibility) are met. However, always verify with your panel documentation and a qualified electrician to ensure the installation meets Canadian Electrical Code (CEC) requirements for your specific application.
