Vacuum contactors use vacuum interrupter as switching elements. Vacuum medium has good isolation and arc extinguishing ability.
R Serial Vacuum Contactors
R series AC vacuum contactor is a enclosed type and high power 3-phase AC contactor, including models of R160, R250, R400, R500, R630 R800 and R1250.This series of contactors have 3 groups of mainmake contacts; R160 and R250 have 3 groups of bridge type make auxiliary contacts and one group of bridge type break auxiliary contact; R400, R500,R630 and R800 have 4 groups of bridge type make auxiliary contacts and 2 groups of bridge type break;auxiliary contacts; R1250 and R2500 has 2 groups of bridge type make auxiliary contacts and 2 groups of bridge type break auxiliary contact; and R1250;can be extended to 6 groups of bridge type make auxiliary contacts and 6 groups of bridge type break auxiliary contact according to customer's using status.The rated current of R series AC vacuum contactor's main contact load is up to 160A-2500A, working voltage 380V-1500V, auxiliary contact load up to AC 12A, 240V.
Circuit Breakers List
Features of vacuum Circuit breaker: Small contact stroke, small size, light weight, low operating power, quick, short arcing time. Isolation performance of the contacts is good after arc-extinguishing, failure capability is better around breaking area; slight combustion loss when breaking the current of contactors, long life, low noise; Used in high frequency operation. Features of permanent magnet vacuum Circuit breakers: This breaker adopts bistable permanent magnet mechanism, the integrated design of mechanical manual closing mechanism and mechanical manual opening mechanism. Permanent magnet mechanism opening is combined with spring opening, the distribution of opening speed is more ideal. Compared with spring operating breaker, movable units are less, significantly improving reliability and life, they are ideal replacement for spring operating breaker.
Isolating Switches List
(1).Features of air isolating switches: Small size, high volume, simple structure, they have obvious isolating fracture and can replace the imports. (2).Features of vacuum isolating switches: Small contact stroke, short arcing time, small size, simple structure, portable operating, they have extremely high breaking capacity. (3).Features of loading isolating switches: They have obvious isolating fracture with air and vacuum breaking capacity. Small contact stroke, short arcing time, high breaking capacity, maintenance-free.
