QO-HID
QO arc-fault circuit breakers provide branch feeder
protection (i.e. QO115AFI) or combination protection (i.e.
QO115CAFI) as required by the NEC and local code
adoption, and comply with UL1699.
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.

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.

Qwik-Gard® circuit breakers provide overload and short
circuit protection, combined with Class A ground fault
protection. Class A denotes a ground fault circuit
interrupter that will trip when a fault current to ground is 6
mA or more, for people protection. Do not connect to more
than 250 feet of load conductor for the total one-way run to
prevent nuisance tripping.
