This series is particularly suitable for the small and middle users, the possibilityy of have thin regulations of the first step it allow to the plant of follow small variations of inductive load particularly interesting for the small user. The different configuration possible on the AN30 serie are suitable for all uses: from standard work cycle to 24h/24; from lower harmonic distortion to middle (THDic max allowed on the capacitors form 50% to 90%) For all systems are used load break switches with pre-opening contacts, and banks are protected by a set of three HRC fuses (NH00 type-curve gG) with high breaking capacity (100kA). For high reliability each bank of capacitors is controlled by its own three-pole contactor, to limit the switching on inrush current each contactors is provided with resistors. Rated voltage of the auxiliary circuits 380V 50Hz (other available on request). The ventilation is made by channels for natural air circulation and are equipped with latest microprocessor regulator IRIenergy type MRK with backlit LCD display multilanguage with text and icons and programmable alarm with possibility of remote control. The capacitors used, IRIpro, are self-healing high energy density polypropylene metalized single-phase with overpressure safety device and discharge resistor, PCB free. For the Easy line we use capacitors with Un 440V rated voltage; for Techno Life line we use capacitors with Un 500V rated voltage; for Power Long Life line we use capacitors with Un 550V rated voltage and for Power TOP LIFE line we use capacitors with Un 600V rated voltage. For particular heavy use is also available the Extreme line with special capacitors 3In/4In (see page 38) AN30 series is made for wall installation, cable entry form bottom, maintenance form front plant, capacitors climbed on threaded plate, metal case in a strong steel sheet and painted with epoxy resin RAL7035.
