Current ratings: See table I. High inrush: Applies unless otherwise

18、 specified. 1/ Voltage ratings: See table 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

19、inductive to 50 V dc. Tripping-time delays: See table I and table II. Terminal and mounting hardware: See figure 1. Terminals: See figure 1. Solderability is applicable to auxiliary contact terminals. Actuator strength: 25 pounds. Actuator operating force: 4 pounds, maximum. Terminal strength: Appli

20、ed load: 30 pounds. Applied torque: 10 inch-pounds. Interrupting capacities: 2,000 amperes at 50 V dc. 2,000 amperes at 120 V ac, 60 Hz. 1,500 amperes at 120 V ac, 400 Hz. 1,000 amperes at 240 V ac, 60 and 400 Hz. Seal: Panel seal test applies. Part or Identifying Number (PIN): The PIN to be catalog

21、ed and stocked by the Government consists of the prefix M55629/20 and two succeeding code letters as follows: 1/, 2/ M55629/20 E M Single pole circuit breaker with panel seal and auxiliary contacts. Current rating code, see table I. Voltage, frequency, and time delay curve code, see tables I and II.

22、 _ 1/ Special PINs for equipment manufacturers use only. Equipment manufacturers who do not require the high-inrush feature or auxiliary contacts in specific production applications may order circuit breakers without these features by modifying the prefix as follows: M55629/20XX: Replace slash with

23、A for items without auxiliary contacts (M55629A20XX). Replace slash with B for items without the high-inrush feature (M55629B20XX). Replace slash with C for items without either the high-inrush feature or auxiliary contacts (M55629C20XX). 2/ Replace slash with D for items requiring configuration 2 (

24、M55629D20XX). Replace slash with E for items requiring configuration 2 without auxiliary contacts (M55629E20XX). Replace slash with F for items requiring configuration 2 without the high-inrush feature (M55629F20XX). Replace slash with G for items requiring configuration 2 without the high-inrush fe
