Siemens BQD360 Circuit Breaker

Siemens BQD360 is a 60 Amp, three-pole molded‑case circuit breaker designed for 480Y/277V AC systems. Part of the Siemens BQD series, it provides thermal‑magnetic protection with both long‑time and instantaneous trip functions and a maximum interrupting rating of 14 kA at 480V. The unit is bolt‑on mounted for panelboard installations and carries a continuous current rating of 60 A at 40°C, making it suitable for protecting feeders and branch circuits in commercial distributions. In practical use, the 3‑pole design ensures simultaneous disconnection of all three phases for safe shutdown during faults or maintenance. This BQD360 device is intended for 480Y/277V networks and aligns with Siemens low‑voltage distribution catalog specs for the BQD/CQD product family, delivering reliable protection for equipment and wiring in 3‑phase applications.
