Switches VB5
Safety switches VB5
Switches comply with the requirements of the European rules EN81 and the Elevator Safety Rules ТУ У31.2-03967731-010-2004,
Purpose
Switches are designed for switching the electrical circuits of alternating voltage 110 V (VB5-3-220V) and 380 V with frequency of 50 Hz or 60 Hz and a direct voltage of 220 V and are used to complete the telescopic central opening of the cabin doors and passenger elevator wells.

General characteristic
| Rated insulation voltage, В | 660 |
| Rated thermal current, А | 10 |
| Protection level according to ДСТУ EN 60529 | ІР00 |
Service conditions:
| Сommutation wear resistance at a DC voltage of 130 V and current value of 2 A, alternating current of 110 V, current value of 0.02 A and with frequency of 1200 cycles per hour is not less than 3 000 000 cycles of ВО for VB5 and 1500 000 VB5-1, VB5-2, VB5-3. |
| Switches reliably commute the lowest operating current value of 0.01 A at direct voltage of 24 V |
| The environment is non-explosive, does not contain current-carrying dust and corrosive gases able to break metal and insulation. |
