MPT420 Pilot Series starting contactors operate in sequence to energize a portion of the motor windings on start which reduces inrush current to approximately 65% of normal. An adjustable timing relay is provided to control time between reduced current start and normal running operation. Metron’s new patented fire pump controller with integral transfer switch is designed in a single narrow enclosure to reduce the amount of pump room space required. Only the highest quality components, UL Listed or Recognized, are used throughout to assure the best possible reliability. The cabinet is fabricated of heavy 12 gauge reinforced steel, with Type 3R supplied as standard and rated 40°C standard, 50°C optional. All field wiring and service connections may be made from the front, allowing the controller to be mounted flush against a wall.Metron fire pump controllers conform to the latest requirements of the NFPA 20, UL 218 and FM 1321/1323, and bear the labels of Underwriters Laboratories and Factory Mutual.
