BQD6270 – SIEMENS 2P70A 347V BOLT ON 14kA BREAKER
The BQD6270 SIEMENS 2P70A 347V Bolt-On Circuit Breaker is designed for reliable performance in high-demand environments. With a 14kA interrupting capacity, this sturdy breaker offers superior protection for your electrical systems. Ideal for both commercial and industrial applications, it ensures safety and efficiency for all your circuit needs.
The BQD6270 is rated for 347 V, uses a bolt-on (rather than plug-in) mounting, and carries a 14 kA interrupting capacity — all characteristics aimed at commercial and industrial panelboards. Standard residential Siemens QP or BL breakers are typically rated 120/240 V and use a different mounting interface, so the BQD6270 is not interchangeable with them.

The BQD6270 is rated for 347 V, which is the phase-to-neutral voltage in a 600 V three-phase system common in Canadian commercial buildings. While a higher-voltage-rated breaker can technically operate at lower voltages, you should always match the breaker to the panel's listed specifications and verify with the manufacturer or a licensed electrician before installation to ensure code compliance.
