Characteristic Codes M135168BII-175 spec. code meanings

Code Translation
AAQL The style designation indicating the configuration that most nearly corresponds to the appearance of the body.
ADAT A measurement taken at right angles to the length of the body, in distinction from thickness.
ADTV The element, compound, or mixture of which the case is fabricated, excluding any surface treatment.
AEBP The center to center distance between terminals parallel to the length of the item.
CPRH Indicates the type of electrical condition that will cause the device to trip.
AEHA The distance between centerlines of mounting facilities parallel to the width of the item.
AEBY The distance between centerlines of mounting facilities parallel to the length of the item.
CPLM The maximum current load that each pole is rated to carry continuously.
CPRG Indicates the type and value of the maximum short circuit current that the item will successfully interrupt, per pole, at the specified rated voltage, expressed in amperes.
AXHR Indicates the type and number of facilities by which the item is mounted.
CPRF Indicates the type and value of operating voltage for which each pole is designed to operate, expressed in volts.
AFJN The measure of sensitivity of the item to be packaged. a factor used by packaging engineers in devising proper cushioning in a package.
BBRG Indicates the type of storage space required for an item in order to provide the degree of protection necessary to maintain serviceability standards.

CPSM The basic internal electrical configuration of the trip mechanism.
CPRQ The means provided to reposition the mechanism so that the device is ready to function.
ABHP The dimension measured along the longitudinal axis with terminated points at the extreme ends of the item.
AKPX The number of poles included in the item.
ZZZK The document designator of the specification or standard which established the item of supply.
TTQY Indicates the type and number of terminals for providing electrical connection.
TEST The specification, standard, drawing, or similar instrument that specifies environmental and performance requirements or test conditions under which an item is tested and establishes acceptable limits within which the item must conform identified by an alphabetic and/or numeric reference number. includes the commercial and government entity (cage) code of the entity controlling the instrument.
CQWN The length of time, expressed in seconds, that an overload may exist before the device will trip at a specified continuous current.
CRCF The temperature of the medium surrounding the trip release at which it can be operated continuously.
CPRL Denotes the type of trip release action.
CPRJ The means by which the trip mechanism is released.
CPRN The continuous current rating per pole at which the device must trip in a specified time, expressed in percent.
AEBV The length of a straight line which passes through the center of an unthreaded mounting hole, and terminates at the circumference.

Technical Definition

Circuit Breaker, also referenced with federal logistics item name code 00136 - A device with means other than fuses for automatically opening the circuit in which it is installed when the current varies from the predetermined value for which the device is set. may include provisions for manual operation. at least one set of contacts must be in series with the actuating element(s). a combination of semiconductor and passive devices may be used in lieu of contacts. for automatically operated items in which the actuating (tripping) element and contacts are not in series, see relay (as modified). for items which are operated both manually and automatically but the actuating elements and contact are not in series, see relay-switch. excludes circuit breaker box and magneto "breaker" assemblies. see also switch (as modified); and controller.
