QO-EPD/EPE Circuit Breakers
QO 1P
With Shunt Trip
QO-EPD/EPE circuit breakers provide overload and short circuit protection combined
with Class B ground fault protection. They are designed to provide ground fault
protection of equipment at a 30 mA level (EPD) or 100 mA level (EPE). They are not
designed to protect people from electrical shock.

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.
