SIEMENS Q Series 20A Single-Pole Breaker
The SIEMENS Q120HID is a new miniature circuit breaker rated at 20 amps and 120 volts AC. It uses a plug-in mounting style with a toggle actuator and fits Siemens EQ load centers. The device carries a 10 kA interrupting rating at 120V AC and accepts wire sizes from 14 to 8 AWG via lug terminals. It is designed for high-intensity discharge lighting circuits in residential or light commercial panels.
Suits installers fitting HID lighting loads
Electricians wiring high-intensity discharge lighting on a Siemens EQ load center will find the correct ratings and plug-in form factor here. Buyers who need a different amperage, a two-pole configuration, or a breaker for a non-Siemens panel should look at other options. This unit is not rated for DC applications and does not fit panels outside the EQ series.
10 kA interrupting rating at 120V AC
The maximum AIR rating of 10 kA at 120V AC is the key specification that determines whether this breaker meets the fault-current requirements of the installation. Verify the available short-circuit current at the panel before selecting this device.

Questions about this item
Should I choose the 20 A single-pole version for a standard 120 V branch circuit?
Yes, this breaker is rated 20 A, 1 pole, 120 V AC and fits Siemens EQ load centres for typical branch-circuit protection.
What does the 10 kA rating mean when the breaker is installed in my panel?
It indicates the breaker can safely interrupt up to 10 000 amps of fault current at 120 V AC without damage.
Does the plug-in mounting work with any load centre or only the EQ series?
The plug-in design is compatible specifically with Siemens EQ load centres; it will not fit other manufacturers' panels.
