Metron/Metron-Eledyne Fire Pump Controllers conform to the latest requirements of Chapter 7, National Fire Protection Association Pamphlet 20, Standard for Centrifugal Fire Pumps, as adopted by Underwriters Laboratories and Factory Mutual. They are withstand rated and listed by Underwriters' Laboratories and approved by Factory Mutual Research Corporation. Sizes range from 15 to 700 horsepower, 200 to 600 volts, 60 Hz. These controllers are for use on Across-the-Line type installations. Only the highest quality components, all UL listed or UL recognized are used throughout to assure the best possible reliability. The cabinet is fabricated of heavy gauge reinforced steel with drip-proof hood. All field wiring and service connections may be made from the front, allowing the controller to be mounted flush against a wall. The controller is completely wired, assembled, and tested at the factory before shipment, and ready for immediate installation.
