STATIC CONTACTOR WITH OVERVOLTAGE PROTECTION
Field of use:
Static contactors are used to transmit time codes to the track circuits in the electrodynamic centralization and automatic line block installations.
• The static contactors have the role of circuit breakers for the supply voltage of the track circuits at a maximum current of 10 A, with the variation of the control voltage between 160-240 V. The switching is ensured by a group of two thyristors controlled in d.c.
The voltage drop in the “connected” state is less than 1.2 V in the case of the static contactor and 2.5 V in the case of the static contactor with protection;
