Clearance is the shortest direct air path over the top of the rib Creepage patti follows the contour of the rib. NOTE Ttic temperature limits of table 13 are based on the values speciticct in lEC Since itiese values arc under consideration, it will be necessary to review tliem.
The overcurrent relay shalf not trip when the output current is less han tOO niA. During these tests, a movement of the actuating member on the actuating means is acceptable provided this does not result in an incorrect indication of the switch position.
Ignition of the cotton shall not occur.
Testing and measurement techniques – Section 2: The connection to the test load to be performed for the two tests is symbolized in fable 2 by an auxiliary switch A. General requirements lEC The switches are mounted as in normal use in a horizontal panel, with the operating means protruding, and the force fs applied once.
In cases wfiere basic insulation and supplementary insulation cannot be tested separately, the insulation provided is subjected to the test voltages specified or reinforced Insulation. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
Alternating current three-phase or 3 a,c. Tests at high speed, however, have to be performed according to Such screws shall not be of metal which is soft or liable to creep, such as zinc or aluminium.

Care a taken that the f. It shall be obvious how the insertion and disconnection of the conductors are intended to be effected. Where this is not practical on the specimens to be used for the test of clauses 16 and 17, the test of If the threads are of metal, the torque Is 1,8 Nm.
Principles, requirements and tests lEC For small helical springs and the like, and for inaccessible parts exposed to abrasion, 61058- layer of grease may provide sufficient protection against rusting. All grease is removed from the parts to be tested, by immersion in an appropriate cleaning agent for 10 min.
Detachable parts are removed.
NOTE 7 Attention is drawn to the fact that solenoid operated pneumatic means may result in an unintentional synchronization. The temperature is measured 2 min after the end of the period. During the test, emission of flames or burning particles shall not occur.
If the document is revised or amended, you will irc notified by email. Need more than one copy? For the following tests the electronic switch Is mounted as in normal use and is loaded as specified in clause 17 so that at the rated voltage the rated load will be obtained.
The clearance and creepage distance requirements of 20 1 and Traces of rust on sharp 61508-1 and any ied film removable by rubbing are ignored. Such screws shall not, however, be used if they are likely to be operated by the user or installer, unless the thread is formed by a swaging action.
NOTE For guidance concerning the levels, see clause Protection against electric stnock lEC For electronic switches, the eleclrical conditions are those specified in table NOTE The classificatton using the ambfent air temperatura 35 ‘C may aiso be used for other electronic switches under the provision that they are properly marked according to No.
The requirements of the quality control system may be met by other means, 5. NOTE 4 A toad is necessary for the switch to be in the on-state.
