Switches VP 73
Travel switches of semi-momentary action VP 73 with double bridge
ТУ У 31.2-03967731-012:2012
Purpose
Switches are designed for switching of electrical control circuits of alternating current with frequency of 50 and 60 Hz with voltage up to 380V and direct current with voltage up to 220V under the driven by switching strips at certain points of the monitored object tracks. Switches are manufactured for installation on mobile and fixed parts of stationary machines in elevators and other equipment. .
Travel switches ВП73 (are similar to МП 1000, ВБПЛ -4) have a double, galvanically separated bridge contact that meets the increased safety requirements in accordance with the Elevator Safety Rules ПБ 10-558-03. .
