GTW88 Air Circuit Breaker (DW45)

GTWEE series intelligent universal circuit breakers could be used for controlling
the low voltage distribution net and keeping it safety. Installing in the low voltage di-
stribution panels, it works as master switch to play general safety role. Its technical
nature has reached the international advanced standard of that kind of products in 1990s.

higher humidity would be permitted, but the lowest average temperature in a month
not exceeding +25℃ during the most moist moth, and the maximum monthly average
relative humidity not exceeding 90% in that month, and giving consideration the dews
on the goods surface, which would appear due to temperature change.
● Pollution protection: 3 grade.
● Installing categories: Ⅳ for breaker main circuits, coils of under voltage release
and primary circuit of transformers; Ⅲ for other auxiliary circuits and control circuit.
● The breaker used on ships and in humid tropical area can work normally
without influence of humid air. salt fog and mildew.
● The breakers used on ships can operate reliably under normal vibration.
● The breakers should be installed according to stipulations in operation manual.
For breakers in common use, the vertical gradient isn't more than 5°,for that used on
ships, the vertical gradient isn't more than 22.5°.
● The breaker should be put in the place where there isn't any explosive medium
and conductive dust and no gas which would corrode metal or distroy the insulation.
● The breaker should be installed in compartment of switch- board and door frame
should be fixed additionally. Protection grade is up to Ip40.
