DETAILED DESCRIPTION

This series is particularly suitable for middle/big users, the modularity and easy expansion allows of follow the growth of the users in any moment and with the minimum of necessary expense. The different configuration possible on the AN300 series 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 typecurve 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
230V 50Hz (other available on request). Forced ventilation made by fun for each module with thermal relay for fun and block; are equipped with latest microprocessor regulator SARenergy type MRK with backlit LCD display multilanguage with text and icons and programmable alarm with possibility of remote control. The capacitors used, SARpro, 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. AN300 series is made for floor installation, cable entry form bottom, maintenance form front plant, capacitors climbed on rack, metal case in a strong steel sheet and painted with epoxy resin RAL7035.
