Classification

• According to the mounting: fixed and draw-out
• According to the poles: three poles, four poles
• According to the operation ways: motor and manual (maintenance and repair)
• According to the release: inteligent over current controller,under-voltage instantaneous (or delay) release,and shunt release
• The capability of the intelligent over-current controller:
• classification: H type (normal), M type (normal intelligent), L type (economic)
• has the function of overload long delay reverse time limit protection
• single phase earthed protective function
• indication function: setting current indication, action current indication, each wire voltage indication(should mention as you order).
• Alarm function
• Self- diagnostics function
• Test function

Environment Condition for Operation and Installation

• Ambient temperature: -5℃ ~ 40℃, and average temperature in 24 hours below +35℃ (except for special orders).
• Elevation of installation site: ≤2000m.
• Relative humidity: Not exceeding 50% at he maximum ambient temperature of +40℃. With lower temperature, higher humidity would be permitted, but the lowest average temperaure in a montn not exceeding +25℃ during the most moist month, and the maximum monthly average relative numiaty not exceeding 90% in that month, and giving consideration to the dews on the goods surface, which would appear due to temperature change.
• Pollution protection: 3 degree.
• Installing categories: Ⅳ for breaker’s main circuits, coils of under voltage release and primary circuit of transformers; Ⅲ for other auxiliary circuits and control circuit.
• The breakers used in ships and in humid tropical area can work normally without influence of humid air,salt fog and mildew.
• The breakers used in ships can operate reliably under normal vibration.
• The breaker should be installed according to stipulations in operation manual. For breakers in common use, the vertical gradient is not more than 50, for that used on ships, the vertical gradient is not morethan 22.50.
• The breaker should be put in the place where there is not any explosive medium and conductive dustand no gas, which would corrode metal or destroy the insulation.
• The breaker should be installed in compartment of switchboard and doorframe should be fixed additionally,protection grade is up to lP40.

Technical Data and Capability

The rated short circuit breaking capability and short time withstand of the breakers, the arcing distance is “zero” (as the outside of the breaker is no arcing.)Table 2

The maximum destroy power is 360W for the breakers, and in the different temperature,and rated lasting current will change.Table 3

Intelligent over current controller protection feature and functions The setting and error.Table 4

Long delay over current inverse time ooperation features I2TL, =(1.51lr1)2tL, and its action time(1.02-2.0) Ir1, has time error is ±15%. Table 5
