H01H33/02 - CPC Classification

Classification description:

High-tension or heavy-current switches with arc-extinguishing or arc-preventing means Details

Sub-classes:

H01H2033/028 » {the cooperating contacts being both actuated simultaneously in opposite directions} 26
H01H33/021 » {Use of solid insulating compounds resistant to the contacting fluid dielectrics and their decomposition products, e.g. to SF } 14
H01H33/022 » {particular to three-phase circuit breakers } 91
H01H33/025 » {Terminal arrangements } 52
H01H33/027 » {Integrated apparatus for measuring current or voltage} 58
H01H33/04 » Means for extinguishing or preventing arc between current-carrying parts 62
H01H33/24 » Means for preventing discharge to non-current-carrying parts, e.g. using corona ring 33
H01H33/26 » Means for detecting the presence of an arc or other discharge 36
H01H33/28 » Power arrangements internal to the switch for operating the driving mechanism 28
H01H33/42 » Driving mechanisms 189
H01H33/44 » Devices for ensuring operation of the switch at a predetermined point in the ac cycle 1
H01H33/46 » Interlocking mechanisms 9
H01H33/53 » Cases ; Reservoirs, tanks, piping or valves, for arc-extinguishing fluid; Accessories therefor, e.g. safety arrangements, pressure relief devices 109
H01H33/59 » Circuit arrangements not adapted to a particular application of the switch and not otherwise provided for, e.g. for ensuring operation of the switch at a predetermined point in the ac cycle 72
