are 600 Vac maximum rated devices with

interchangeable thermal

magnetic or electronic

trip units rated 600A maximum continuous

current. The circuit breaker uses noninterchanageable

trip units and is factory sealed.

Refer to Table 1-1 for all available trip unit ratings.

This instruction leaflet (IL) gives procedures for installa

tion and field testing of Q

Percent Rated L

Frame Circuit Breakers

Q-Frame circuit breakers are suitable for conrtinuous

operation at 100 percent of the frame rating

used with 90°C insulated wire and AL9CU

terminals in an

enclosure which measures at least 24

high x 15

wide x

deep. The minimum required ventilation is 8 sq. in. top

front and 8 sq. in. bottom front.

INSTALLATION

The installation procedure consists of inspecting the cir

cuit breaker and, as applicable, installing the trip unit and
