I-T-E Max-Flex
Types 1, 3R, 4, 4X, 12
General Information
The l-T-E Max-Flex Flange-Mount Handle Operator is a flex-
ible cable control device used for the remote switching of a
circuit breaker within an enclosure. The flexible cable is
connected directly to the breaker at one end and to a pre-
assembled switch handle operator at the other end. The
remote operator handle, located on the enclosure flange, is
used to perform mechanical open/close switching opera-
tions. This is accomplished through the flexible control cable
Function
The advanced design concept of the Max-Flex Flange-Mount
Handle Operator provides for greater flexibility when locating
a circuit breaker within an enclosure. The circuit breaker can
be mounted almost anywhere, at any angle and on almost any
convenient surface. The same flexibility applies when locating

Application
The Max-Flex Operator is designed to work with l-T-E circuit
breakers having current ratings through 1200 amperes. The
Max-Flex unit meets all the industrial criteria such as UL and
Automotive Industry Standards.
Design
The new Max-Flex Handle Operator provides maximum flex-
ibility in design and assembly of electrical equipment.
The cable design is flexible and rugged. The flexible cable
comes in standard 4 or 5 foot lengths. However, specific
lengths can be special ordered up to 20 feet.
Operation
When properly installed, the Max-Flex Handle Operator is
used to perform remote switching operations from outside of
the enclosure. Switching is accomplished by pushing the
Max-Flex Handle Operator up for ON and down for OFF. The
mechanical advantage gained with this device simplifies switch-
ing operations when compared with local switching at the
breaker
Interlocking provisions are included and described below. All
switching functions are standard according to accepted
practices.
