GUARD AS 4505968 - Caterpillar

(1) - Single bearing generator(2) - Generator includes a Permanent Magnet (PM) exciter(3) - Harsh environment generator(4) - Form wound generator(5) - Main stator insulation: coastal insulation protection(6) - Two-bearing generator(7) - Self-excited generator(8) - Random wound generator(9) - Main stator insulation: 1 vacuum impregnation(10) - Marine Society Approved generator. Meets requirements of ABS, Lloyd's & DNV.(11) - Stator insullation: 1 vacuum impregnation and 1 dip of epoxy(12) - Main stator insulation: 1 vacuum pressure impregnation and 1 dip and bake in epoxy resin(13) - Medium voltage generator(14) - All generators have 10 leads except 800 frame models. The 800 frame models have only 4 leads. The 800 frame generators have only the higher voltage and are not reconnectable.(15) - LS = Low Speed (1200 RPM).(16) - Tropicalized generators that were built to customer order prior to standardizing on this insulation system for all generators. This change was effective with S/N 100-Up.(17) - First production release that used thermal protector (Klixon Breaker) in regulator assembly. Standard on all SR4 generators effective with S/N 5N-300 and Up.(18) - Generator includes space heater in accordance to Marine Society Specifications.(19) - Generators rated 3 phase, 60 Hz, 240-480 Volts also used for 3 phase, 50 Hz, 200-400 Volts at nominally 80% of 60 Hz kilowatt rating.(20) - Generators rated 3 phase, 60 Hz, 300-600 Volts also used for 3 phase, 50 Hz, 240-480 Volts at nominally 80% of 50 Hz kilowatt rating. All generators S/N 3000-Up will have series boost capabilities.(21) - Many of the generators included have series boost capability(22) - Generators include space heaters(23) - Oil field generator(24) - Generators for standby service only(25) - Generators for prime power service only(26) - 3 phase, 4 pole generator(27) - 3 phase, 6 pole generator(29) - Generator for use with power modules(30) - Main stator insulation: 2 dips and bakes in epoxy resin(31) - Main stator insulation: 4 dips and bakes in epoxy resin
