Capacitor Duty Contactors
Capacitor Duty Contactors are specially design to meet capacitor switching applications. They are fitted with contact block of 3 early make auxiliary contacts in series with quick discharge damping resistor to limit pick current to the value within contactor making capacity such that normal rated capacitor current is carried by main contacts which, after closing, effectively by-pass the damping resistors. These contactors conform to IEC 947-4-1 & IS 13947-4-1.
Capacitor Duty Contactors, 3 Pole, are available in 8 ratings to meet exact applications need in ratings 10 kVAR;12.5 kVAR; 16.7 kVAR; 20 kVAR; 25 kVAR; 30.3 kVAR; 40 kVAR; 60 kVAR., suitable for clip-on or base mounting.
It has provision of 1 NO + 1NC or 2NC auxiliary contacts & extra auxiliary contacts are feasible by using side snap-on blocks. The contactors are suitable for operating temperature of 50 degree C without de-rating.
