Safety locks low-voltage PN2P 400/400 A
Safety locks low-voltage PN2P series
This production is certified by OS "The international standards and systems No. UA1.093.0003155-11 and conforms to requirements of GOST 17242-86, TU U 31.2-37056635-003:2010.
Safety locks the fusible PN2P series are intended for protection of electroinstallations and electric chains of alternating current of 380/220B of industrial frequency of 50 and 60 Hz and a direct current - 220B at short circuits and overloads.
PN-2 safety locks
Highly effective protection of distributive networks of a low voltage - here the main task of low-voltage safety locks. Products are used as means of protection of electroinstallations with tension 380B from overloads and currents of short circuits. From the moment of emergence of electricity in a mankind arsenal, installation of such means of protection as fusible low-voltage safety locks on some sites of power supply do energy of electric current safe. Operation of electroinstallations with fuses prevents emergence of the fires and serious accidents.
PN-2 safety locks description.
Depending on model of an insert work at course of electric current with a force from 30 to 630 And that allows to use them in the most various systems of power supply. The low-voltage safety lock represents the fusible insert placed in the strong case from electrotechnical porcelain. The internal hollow space is filled with quartz sand. When passing through a safety lock of current the insert which melts works, and the arising arch is extinguished by thickness of sand. Thanks to the fact that quartz sand and porcelain are nonflammable materials use of safety locks protects electroinstallation from fire emergence. One of the most important advantages of this production is simplicity of their replacement. Replacement is carried out by specially trained personnel having the corresponding qualification. Also production can be not disposable, and and remontnoprigodny. In case of operation, safety locks can be handed over on restoration (the fusible insert changes and new quartz sand is filled up). In a regular operating mode of a product are durable, and eventually do not change the main characteristics.
The low-voltage production offered by us is intended for use in any electroinstallations, an exception are installations which function in an explosive environment.
Low-voltage safety locks it is available and reliable protection of your difficult system of power supply.
