The switch is designed to protect electric installations of outflows of short circuits as well as for infrequent operational switching-on and switching off of electrical circuits under normal operating conditions in three-phase AC networks with isolated neutral.
The switch is designed to work in mines that are not dangerous for gas or dust and in workings with fresh air of mines of I and II categories in gas or dust hazardous according to NPAO 10.0.-1.01-10 "Safety Rules in Coal Mines" as well as in underground mines of mines (with the exception of workings in which the gas regime has been introduced in warehouses of fuels and lubricants and explosives) according to NAOPOP.0.00-1.34-71PB 03-553-03 for Russia) "Uniform safety rules for the development of ore, nonmetallic and alluvial deposits by underground method "and" Safety rules for the development by underground mining of salt deposits of the Republic of Belarus. "
Execution is a normal normal PH1.
The voltage is 380; 660; 380/660 V.
Current - 32; 63; 80; 125; 160; 250 A.
Complete set - switches of series A3710, A3720,
ВА57-35, ВА04-36- of manufacture ХЭМЗ, ДЗНА, КАЭЗ, the Contactor according to the wish of the customer.
Management - local; On the customer's request, remote disconnection via intrinsically safe circuits can be realized.
Protection - from short-circuit currents with adjustable and fixed setpoint; from a decrease in the insulation resistance of the outgoing circuits; possibility of connecting an external leakage relay
Indication - upon customer's request it can be equipped with a voltage indicator
Advantages - lightweight and durable housing, modern circuitry, high level of unification with the starter 1PRN.
Trolleys V / 1 N are intended for transportation of people on mine workings with an inclination corner from 6 ° to 30 ° on rails of P24 or RZZ type of 550, 575,600,750 and 900 track mm.
The complex of repairing works includes (if available)
For decorative and antiseptic painting of wood products in domestic and industrial conditions.
