BQD6230 – SIEMENS 2P20A 347V BOLT ON 14kA BREAKER

The BQD6230 is rated at 347V, which aligns with Canada's standard 600Y/347V distribution systems widely used in commercial lighting and industrial branch circuits. Its 14kA interrupting capacity also meets the fault-current requirements of many commercial panelboards, making it a practical choice for Canadian electrical systems under the Canadian Electrical Code (CEC).

The BQD series has seen limited availability through standard distribution channels, making units like the BQD6230 increasingly difficult to source. Northern Breaker Group specializes in obsolete and hard-to-find breakers, and we maintain stock of legacy Siemens BQD units. Contact our Calgary, Edmonton, or Vancouver counters or request a quote online for current availability.

A bolt-on breaker physically bolts to the panelboard bus bar, providing a more secure mechanical and electrical connection — preferred in commercial and industrial panels subject to vibration or higher fault currents. A plug-in breaker clips onto the bus. The BQD6230 is a bolt-on type, so its replacement must also be a bolt-on breaker compatible with your panel's bus. Substituting a plug-in unit is not appropriate and may not be code-compliant. Contact us to confirm the correct replacement for your application.
