The SIEBQD6125 is a Siemens 1-Pole 25 Amp 347V Bolt-On Circuit Breaker, designed for reliable overcurrent protection in various electrical applications. Compact and efficient, this breaker features a robust design for easy installation and long-lasting performance. Ideal for commercial and industrial use, it ensures your equipment remains safe and operational.
The Siemens BQD frame is rated for 347V operation, making it suitable for Canadian 347/600V commercial and industrial distribution systems. Standard QP (plug-on) and BL/BA (bolt-on, 120/240V) breakers are rated for residential-grade voltages and are not appropriate for 347V branch circuits. The BQD is also a bolt-on design, requiring a compatible commercial panelboard with bolt-on bus connections.
Yes — 347V single-pole breakers like the SIEBQD6125 are a standard choice for fluorescent and LED lighting branch circuits in Canadian commercial buildings, where 347/600V distribution is the norm. At 25A, it provides appropriate overcurrent protection for lighting loads in offices, warehouses, retail spaces, and similar occupancies.
