1.RCCB Application
GSL1 series residual current operated circuit -breaker(hereafter simply reffered to as breakers) are one of the new type of breakers which have been developed by the company using advanced design and manufacturing technology.The rated insulation voltage of the breakers is 800V,suitable for turn-on of turn-off not frequently in the circuit of AC50Hz, rated working voltage 400V and rated working current up to 630A. The breakers equipment against damage may caused by long -term existed earth fault, which can't be examined by the over-current protection device.
2.Matters needing attention
All the performance of the breaker have been set by the company, and it could not be adjusted arbitrarily in use.

The breakers equipment against damage may caused by long -term existed earth fault, which can't be examined by the over-current protection device.
The breakers have the following characteristics: compact size,high breaking capacity, short arc -over distance and shakeproof,etc.
The breakerscould be installed vertically(upring) or horizontally(transverse).
The breakers can't be fed inversely,only allowing 1,3,5 connect with power supply wires,2,4,6 connect wth load wires.
The breakers are applicable to isdation, its corr- esponding symbol is shown as“ The breakers comply with the demands of the following standards;
IEC60947-1 and GB14048.1General
IEC60947-2 and GB14048.2Low voltage breakers and appendix B MCCB with residual current protection
IEC60947-4-1 and GB14048.4Electro-mechanical contactors and motor starters
The breakers acquired the "CCC" certificates approved by CQC (China Quality Centification Center).2.Matters needing attention
All the performance of the breaker have been set by the company, and it could not be adjusted arbitrarily in use.
The rated residual working current and residual current working time (undelay and delay) of the breakers can be adjusted by the users according to actual needs (operated by professionals).
As the main circuit is energized,For the rated residual working time of undelayed of the breaker, Press the button of simulating residual current working test should release immediately. For the delayed breaker,only while,press the test button and remain the adjusted delay time value, the breaker could release.
After the breaker released due to creepage,the creepage indicating button on the panel should be out-protrude.
The breaker with creepage alarm unit module must reset the return button when creepage alarmed,and the creepage protection module of the breaker can work as normal.
3, ORDERING NOTICE
Users should sure of their detailed acquaintance of the products' technological materials and make order by the erdering notice in terms of future applicable situations of the circuit breakers.
The campany would configure by "Factory's setting values of residual current protection"if users had no requirements of protection parameters of
Residual current when makingorder.
Four poles breakers for the share wire of three -phase four-wire 400V/230V or single phase and Three-phase
