Welding Equipment

IEC 60 947, EN 60 947 (VDE 0660). The contactors are suitable for use in any climate. They are safe from touch to DIN VDE 0106 Part 100.. The 3RT16 capacitor contactors are special variants of the size S00 to S3 SIRIUS contactors. The capacitors are precharged by means of the mounted leading NO contacts and resistors; only then do the main contacts close.. This prevents disturbances in the power system and welding of the contactors.. Only discharged capacitors are permitted to be switched on with capacitor contactors. Recommendation: use discharge chokes for parallel connection with the capacitors.. The capacitor contactors of size S00 comprise an NO contact and another unassigned NC contact in the auxiliary switch block fitted to the basic unit.. The auxiliary switch block which is... Less
