Providing essential overload and short-circuit defense, the Siemens BQD360 is a 3-pole, 60A molded case circuit breaker. This SENTRON series device features a non-interchangeable thermal-magnetic trip unit for consistent performance in commercial and industrial applications. It is engineered to mount into Siemens P1, P2, P3, P4, and P5 panelboards using a standard bolt-on configuration. The breaker is rated for 14kAIC at 480Y/277V and 65kAIC at 240V, ensuring excellent fault clearing.
Which panelboards are compatible with the Siemens BQD360 circuit breaker?
The BQD360 is designed exclusively for use in Siemens P1, P2, P3, P4, and P5 series panelboards. It features a bolt-on connection that mounts directly to the panelboard bus.
What is the difference between Siemens BQD and CQD circuit breakers?
While they share the same physical footprint and electrical ratings, their mounting methods differ. The BQD360 is a panelboard-mount breaker that bolts directly to the bus and includes load lugs only. The equivalent CQD breaker mounts onto a standard 35mm DIN rail or a flat surface and includes both line and load lugs.
Do the standard lugs on the BQD360 accept aluminum wire?
Yes, the factory-installed load lugs accept both copper (8 to 1 AWG) and aluminum (6 to 1/0 AWG) conductors. To prevent loose connections and overheating, always tighten the lugs to the exact torque values printed on the circuit breaker label.
Can I wire both the line and load sides of the BQD360 with cables?
No. As a standard panelboard circuit breaker, the BQD360 includes wire lugs on the load side only. The line side requires a direct bolt-on connection to the busbar of a compatible Siemens panelboard.
Is the Siemens BQD360 rated for DC voltage applications?
Yes, this breaker is rated for 125/250VDC with a 14kA interrupting capacity. When applying molded case circuit breakers in DC systems, ensure your wiring configuration matches the manufacturer guidelines for ungrounded or grounded DC circuits.
Does Siemens offer a 600V version of the BQD360 for Canadian applications?
Yes, the Siemens BQD6 series is the CSA-certified version designed for 600Y/347VAC applications. The specific cross-reference for a 60 Amp, 3-pole model is catalog number BQD6360. The standard BQD360 is limited to a maximum of 480VAC.
Is the Siemens BQD360 circuit breaker HACR rated?
Yes, all 1, 2, and 3-pole BQD circuit breakers from 15 to 100 amps, including the 60A BQD360, carry a Heating, Air Conditioning, and Refrigeration (HACR) rating for use with commercial HVAC equipment.
