QO High Intensity Discharge Circuit Breakers (QO-HID)
HID circuit breakers are for use on circuits feeding fluorescent and high intensity
discharge (HID) lighting systems such as mercury vapor, metal halide, or high pressure
sodium. These circuit breakers are physically interchangeable with QO circuit breakers.

QO Key Operated Circuit Breakers (QO-K)
QO-K Key Operated
Key operated QO circuit breakers are available in single-pole construction and can be
mounted in any single-pole space which will accept a standard QO circuit breaker. These
circuit breakers can be turned ON or OFF or to RESET with a special key (catalog
number QOK10) included with the circuit breaker. These circuit breakers are UL Listed
and available as shown in the table.

Non-Automatic (Standard) Miniature Switches
Miniature non-automatic switches have the same physical packaging as miniature circuit
breakers, but open only when the handle is switched to the OFF position.
Non-automatic switches provide no overcurrent protection or short circuit protection.
They must not be used on systems that have an available fault current greater than the
values listed in the table. Non-automatic switches are UL Listed per UL 1087 and are
CSA certified.
