Current ratings: See table I. High Inrush: Applies unless otherwise specified. 1/ Voltage ratings: See tab
18、le II. Ratings are maximum; the minimum operating voltage is limited by the internal resistance or impedance of the circuit breaker (see table I). Auxiliary contacts: Contact capacity shall be 10 amperes to 250 volts 60/400 Hz and 2 amperes resistive, 1 ampere inductive to 50 V dc. Tripping-time del

Current rating code, see table I. 3/ Voltage, frequency, and time delay curve code, see table I and II. 3/ When circuit breakers without auxiliary contacts, are installed in new equipm
23、ent, replacement spares should possess this feature since it is more economical for the DoD to stock one version of this item instead of two. Therefore, stock numbers should not be requested (or assigned) for this special PIN. _ 1/ Special PINs for equipment manufacturers use only. Equipment manufac
24、turers who do not require the auxiliary contacts in specific production applications may order circuit breakers without this feature by modifying the prefix as follows: M55629/22XXXXXX. Replace slash with A for items without auxiliary contacts (M55629A22XXXXXX). 2/ Replace slash with D for items req
25、uiring configuration 2 (M55629D22XXXXXX). Replace slash with E for items requiring configuration 2 without auxiliary contacts (M55629E22XXXXXX). Replace slash with F for items requiring configuration 2 without the high-inrush feature (M55629F22XXXXXX). Replace slash with G for items requiring config
26、uration 2 without the high-inrush feature or auxiliary contacts (M55629G22XXXXXX). 3/ If all poles have identical ratings, code letters will repeat for each pole. If all poles are not identical, poles 1, 2, and 3, respectively (see figure 1) shall be coded in ascending order of the current rating co
