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.
