SONTUOEC 18MM RCBO 25A 1P+N 6KA Residual current Circuit breaker with over
current and Leakage protection
SONTUOEC Economic type 18mm width residual current circuit breaker is in conformity with the
standards of IEC61009.It is 10KA short circuit design ; It can cut
off the fault circuit immediately on the occasion of shock hazard
or earth leakage of trunkline.Thus it is suitable to avoid the
shock hazard and fire caused by earth leakage.It can be used in
circuits up to single phase 230V,three phase 400V,50 or 60Hz.
Normal working & installment conditions
1.Ambient temperature: -5ºC~+40ºC, 24 hours average temperature not
exceed +35ºC.
2.Installment plance altitude: ≤2000m
3.Gas relative humidity:not exceed 50% at +40ºC, higher humidity
allowed at lower temperature.
4.Pollution degree: 2 class
5.Installment condition: Mounted in the place without obvious
impact or shock, no dangerous(explosion) dielectric without
corrosive metal or damaging isolation gas(conductive dust).
6.Installment method: TH35-7.5 mounted rail, can be installed in
distribution board, case or box. Generally mounted vertically.
Tilted angle between mounting face and vertical face not exceed
±5°.
7.Mounted Category: II,III class.

Construction features
1. Measuring component and buckling component of products is
located between enter line end and entrance line end ;
2. Movement characteristic of products can not be changed with
outside mechanical tool ;
3.The operating organization has the free function to take off and
buckle;
4. Operate part can not be taken down from the shell outer of
products ,the shell can not influence the operating organization to
work, the accessory group which replace the feelers pressure
,should guarantee the feelers pressure does not change while
running .
5. Overall and mounting dimensioned chart.
