•
The contactors have increased resistance
to dirt and sand. Thus the Class 81 is ideal
for environments with wind blown dirt
and sand.
•
The coils have a temperature rating
of 155
o
C (0.75 – 20Hp). This high
temperature rating allows the coil to
withstand wider voltage fl uctuations
resulting in fewer coils burning out.
•
The contactors meet the same rigorous
horsepower ratings required by UL as all
our other pump controllers. This means
the high level of reliability you fi nd in our
existing pump controllers are also found
in the Class 81.
•
The contactors are constructed with
the same materials used in all our other
pump controllers. This means the Class
81 contactors are rugged and heavy-duty,
immune to moisture and will not warp or
melt if overheated.
•
The contactors utilized in the Class 81
have been time proven over the past
55 years.
•
The Class 81 utilizes the ESP100 solid-
state overload relay. The circuit board
is conformally coated which gives
it superior protection against high
humidity, condensation and corrosive
environments. You will not fi nd this in
many of the other manufacturer’s
overload relays. Additionally, the
ESP100 provides true phase loss
protection tripping within
three seconds.
•
The width of the smallest Class 81
enclosure is half that of the Class 87
and weighs 40% less. This increases
the ease of installation. Even with the
smaller size, suffi cient panel space is
still provided for fi eld installed devices.
