Electric Zone 786

TeSys Deca contactor, 3 poles (3NO), for switching 3-phase capacitor banks up to 63kVAR@400V 50Hz (104kVAR@690V). It provides a 110V 50/60Hz AC coil, 1NO+2NC instantaneous auxiliary contacts, with front mounted early make poles and pre-wired damping resistors for current limitation. For operating rates until 240 cycles/hour and environments until 60°C, it procures high reliability and durability. Compact (85mm width), DIN-rail mounting or screw fixing. Multi standards certified (IEC, UL, CSA) and compliant with shunt capacitors standard IEC 60831, Green Premium product (RoHS/REACh).

• C&S ‘s range of capacitor duty Contactors is specially designed for capacitor switching applications. As capacitor switching is associated with high inrush current, the Contactors are provided with damping resistors which limit the value of inrush current to a safe value.

Siemens 3TS capacitor duty contactor works on mechanical delatching operating principle, which ensures reliable switching of capacitors as per AC- 6b utilization category
