PRODUCT DESCRIPTION

The protection element also provides a non-sensitive area to avoid instability due to small  asymmetries and unbalances that can generally be present in the network system. This  condition is represented by the characteristic reproduced below, where the hatched area is the tripping zone.

Description:

QO-HM and QOB-HM high-magnetic circuit breakers are recommended for area lighting (such as 

athletic fields, parking lots, and outdoor signs), when using lamps of inherent high inrush current, 

individual dimmer applications or other applications where high inrush currents exceed standard 

tripping conditions. These circuit breakers are available in one-pole 15 and 20 A ratings only. QO-HM 

and QOB-HM circuit breakers are physically interchangeable with standard QO and QOB circuit 

breakers and accommodate the complete range of QO accessories.

QO-HM and QOB-HM circuit breakers are manufactured with the magnetic trip point calibrated at a 

much higher level than standard QO and QOB circuit beakers, as shown in Table 3.

QO-HID and QOB-HID High Intensity Discharge Circuit Breakers

QO-HID and QOB-HID circuit breakers are for use in high intensity discharge (HID) lighting systems, 

such as systems using mercury vapor, metal halide or high-pressure sodium lighting units. These 

circuit breakers are designed to handle the high inductive loads, harmonic currents and cycling which 

are inherent in HID lighting systems. QO-HID and QOB-HID circuit breakers are physically 

interchangeable with standard QO circuit breakers and accommodate the complete range of QO 

accessories.

QO-HID and QOB-HID circuit breakers are manufactured with larger contacts than standard QO and 

QOB circuit breakers to allow switching of high inductive loads. They also have magnetic 

characteristics similar to QO-HM and QOB-HM high-magnetic circuit breakers to allow the circuit 

breaker to hold in against the high starting inrush currents which are typical in HID lighting systems.

QO and QOB Miniature Switches

Miniature switches are intended for use as disconnecting devices only. They provide no overcurrent 

protection. QO and QOB switches are UL Certified for use on circuits capable of delivering not more 

than 10 kA when protected by an equivalent rated circuit breaker or fuse. These switches are available 

in 60 and 100 A rating.

QO and QOB switches are available with auxiliary switches only. (Shunt trip and bell alarm electrical 

accessories are not available on QO and QOB miniature switches.) QO and QOB switches are 

available with the complete range of handle accessories.

QOK and QOBK Key-Operated Circuit Breakers

Key-operated QOK and QOBK circuit breakers provide an alternative means for turning a circuit 

breaker ON or OFF, as well as for resetting a tripped circuit breaker. The circuit breaker is turned on, 

off or reset with a special key included with the circuit breaker. Key-operated circuit breakers are 

available in one-pole construction only and can be mounted in any one-pole space which will accept a 

standard QO circuit breaker. These circuit breakers are available in 10–30 A ratings, with interrupting 

ratings of 10 kA at 120 Vac.

Replacement keys are available separately. Factory-installed or field-installable accessories are not 

available on key-operated circuit breakers.
