About the Series EHU-800
• Have a visible gap or a position indicator that cannot indicate OFF (isolated) until all contacts are actually open and
there is an adequate isolating distance between all the contacts in accordance with IEC 60947-3;
• Have an external operating means (e.g. handle), (
exception:
power-operated switchgear need not be operable from
outside the enclosure where there are other means to open it). The handle should be BLACK or GREY
• Be provided with a means permitting it to be locked in the OFF (isolated) position (e.g. by padlocks). When locked,
remote as well as local closing shall be prevented;
• The handle of the supply-disconnecting switch shall be located between 0.6m and 1.7m above the servicing level.
• The disconnecting switch must have overcurrent and overload protecting functions to initialize them as low as
possible under normal running.
• This disconnecting switch should have leakage current protecting function. The max leakage current should be less
than 30mA.
• The disconnecting switch should have a breaking capacity sufficient to interrupt the largest normal running current
of loads. The breaking capacity required should be selected according to the table given below:
