Capacitor Duty Contactors manufactured and exported by the Controls & Switchgear Group are specially designed to meet capacitor switching applications. All plants of the Controls & Switchgear Group are approved and accredited to ISO 9001 [2000] & 9002. The Capacitor Duty Contactors are fitted with contact block of 3 early make auxiliary contacts in series. It features with a quick discharge damping resistor to limit pick current to the value within contactor. It making capacity such that normal rated capacitor current is carried by main contacts which, after closing, effectively by-pass the damping resistors. These Capacitor Duty contactors conform to IEC 947-4-1 & IS 13947-4-1. The 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. Capacitor Duty Contactors 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.
Features of the Capacitor Duty Contactors manufactured and exported by the Controls & Switchgear Group arev as follows:
