SIEMENS BQD220 20A 2-Pole Circuit Breaker

This miniature circuit breaker from the BQD series provides 20 amps of overcurrent protection for single-phase circuits at 480V AC. It mounts by bolt-on connection and is designed for use with Siemens P1 panelboards. The toggle actuator allows manual switching and clear trip indication.

Check panelboard series and voltage before ordering

Verify that the target panelboard is a Siemens P1 series to ensure mechanical and electrical compatibility. Confirm the system voltage does not exceed 480V AC or 250V DC and that the available fault current is within the 14kA AIR rating. Ensure the mounting rail accepts bolt-on style breakers and that a two-pole slot is free.

Bolt-on mounting and lug terminals simplify

The bolt-on mounting style secures the breaker firmly to the P1 panelboard bus, resisting vibration in industrial environments. Lug terminals accept standard conductors for the 100A frame size, allowing straightforward wiring. The unit operates up to 104 degrees F and measures 4.5 inches long, 2 inches wide and 2.7 inches deep for panel space planning.

Questions about this item

Does the SIEMENS BQD220 come with mounting hardware or lugs, or must they be purchased separately?

The breaker includes bolt-on mounting and a terminal lug connection as part of its design, so no separate mounting hardware or lugs are required for installation in a compatible panelboard.

Should I choose the 20 A, 2-pole version or a different amperage for a 480 V AC lighting circuit?

Select the 20 A, 2-pole model when the circuit load calls for 20 A protection at 480 V AC; other amperages are separate catalogue items and not interchangeable with this breaker.

What does the 14 kA interrupting rating mean when the breaker is installed in a P1 panelboard?

It means the breaker can safely interrupt up to 14 kA of fault current at 480 V AC when mounted in a Siemens P1 panelboard, limiting damage during a short-circuit event.
