Knife switches the switching PRZK - 1-0-2, 3-4 polyusn. on currents 63, 83, 125, 160A. SPAMEL, Poland. The best prices
The power switches of a source of power supply (switching knife switches) - PRZK on currents 63, 83, 125, 160A.
Switches of the PRZK power supply represent the design consisting of two standard isolating RSI switches blocked among themselves by the special mechanism which prevents turning on of the second power supply at included the first. PRZK switches are equipped with a special connector and by that provide the complex solution of switching of sources of power supply, for example Like the Network - the Unit. The connector serves for association of exits of the switch and is the block of crossing points. The connector can be established from above or from below the switch. This opportunity allows to carry out work of the switch in the following modes:
- two inputs of food - one consumer (one loading)
- one input of food - two consumers (two loadings). By means of PRZK switches transition and reliable division between primary and alternative systems of giving of food is carried out, than the continuity in work of the equipment is provided.
Tiporyad of switches of the PRZK power supply meets the last requirements put to the modern low-voltage equipment and correspond to directives: 73/23/EWG and 93/68/EWG.
Switches of the PRZK power supply possess the following properties:
• high electric parameters and reliability of operation of the device it is provided with self-cleaning knife contacts and an effective chamber of a dugogasheniye,
• the reliable mechanism of the drive provides inclusion and switching off independent of the speed of switchings at the operator,
• safety of service is created at the expense of protective terminal covers for the contacts providing degree of protection of IP20 and delivered in standard option
• when fastening to the panel degree of protection of IP65 is provided,
• execution 3 and 4 polar, with N diconnected or which is not diconnected
• fast installation on dynes lath of TS35 or on the assembly panel,
• a possibility of installation in the majority standard switchgears without additional elements (height of the forward panel of 45 mm),
• a possibility of blocking of the drive with providing position of the handle in situation it is switched off (0-OFF) by means of three locks,
• safe assembly clips,
• connection of the raw wires
(without cable tips) with a section up to 70 mm,
• reliable identification of a condition of the switch - the handle always shows an exact condition of contacts,
• the special design of the portable handle provides impossibility of opening of a door of the switchgear in situation is included (I-ON),
• a possibility of emergency opening of a door of the switchgear in the included condition of the switch (according to the special instruction),
• the materials used for production are suitable for secondary processing and are safe for environment.
