To avoid unintentionally tripping a sensitive breaker/switch
into the on/off position, we recommend attaching the APM
HEXSEAL® 1131/60 inverted bellow toggle switch boot.
There are an increasing number of breakers/switches that
when covered with an environmental sealing switch cover
can trip the breaker switch into the off position due to the
mere physics of being covered by the wrong type cover.
APM uses low durometer rubber in many cases to guard
against this tendency. However, there are an increasing
number of breaker/switches where this strategy alone is not
sufficient, and our “Ultra Flex Series” with a bellow design
incorporated therein is very able to combat this problem.
Prime examples of this trend include the CBI “B”/”DD”
frame, Airpax “Snapak” frame, and Carling “M” frame all
with an extremely light spring load on the baton style
actuator handle. These are used extensively by the military,
marine, industrial, construction and commercial industries
around the world.
The Ultra Flex is designed to provide very little or no
resistance to the actuator that would cause the breaker
to trip.
It still provides a UL recognized sealing performance that
meets the NEMA 4, 4X/IP68 sealing standards.
APM HEXSEAL patented the original circuit breaker
environmental sealing breaker cover and associated
electromechanical switch sealing boots 65 years ago
and continues to do so today.
APM’s mission is to provide complete sealing solutions
resulting in total customer satisfaction. The world continues
to evolve technologically, and APM continues to resolve
sealing problems for industry and the military.
