A: 10-32 inserts are provided for front mounting on all units. M5 ISO metric mounting inserts are available and are specified by the eight decision in the part number.

B: The auxiliary switch is located on the left hand pole (viewed from terminal end) unless specified otherwise. Note this is the only location available for breakers rated over 250 amps. The switch is available as an alarm switch (changes state when breaker electrically trips) or as an auxiliary switch (changes state when the breaker contacts change state either from tripping or operation of the breaker handle). See outline drawing for location of alarm and auxiliary switches.Note alarm switches are available only with mid trip option. When both an alarm and auxiliary switch are specified with a metering shunt, only the C and NO or C and NC terminals from each switch are available for field termination.

C: 3/8-16 captive nuts are available for bus bar terminations or crimp lugs (specify front or back termination). 3/8-16 long and short studs are also available (specify front or back mount). A number 6 through 300 MCM Al/CU solderless connector is available (specify front or back mount).

D: Only series construction and DC ratings are available in current carrying poles above 250 amps. Consult factory for special requirements.

E: The coding given permits a self-assigning part number but with certain limitations (due to the adaptability of magnetic protectors to complex circuits), which require a need for a factory assigned part number. Typical examples are units with mixed ratings, combinations of styles, or construction not listed in the third decision table, etc. It is suggested that order entry be by description and/or drawings, and a part number will be established. Additionally, it is standard policy to establish a factory assigned part number wherever a descriptive drawing exists to provide cross-reference, traceability, and manufacturing control.

F: When specifying a protector for AC motor start or high inrush applications, the peak amplitude and surge duration should be specified for factory assistance in rating selection.

G: Since magnetic protectors with time delay are somewhat attitude and temperature sensitive, all trip curves and trip currents are specified with the protector mounted in the normal vertical position at ambient temperature of 25 degrees C. Protectors do not carry current prior to application of overload for calibration test. For other than vertical mount position,consult factory.

H: A 25mV at rated current non-isolated metering shunt is available as an option (see outline drawing). The shunt accuracy is 1% full scale 25 degrees C ambient.

I: Dual coil construction is available below 175 amps only. Consult the factory.

J: Current Ratings decisions referencing this note may be replaced by a factory assigned nondescript number.

K: Single pole unit above 250 Amps are supplied as parallel multi-pole assemblies.

L: Auxiliary switch located in the left hand pole when viewed from the terminal end. All meter shunt and parallel pole builds that require an auxiliary switch will automatically get A-XXX4 type switch. To connect to the switch terminals which are brought through the cover use a Molex 02-09-1104 crimp terminal.

M: Pole with Auxiliary Switch and Gold Contacts.

N: Maximum Voltage and Current; two poles breaking.

O: Terminal Selection and Connect "B0" and "B4" automatically get anti flashover for multi-pole construction. Refer to Outline Drawings.

P: Terminal Selection and Connect "B3" automatically get anti flashover barrier for multi-pole construction with voltage ratings above 250 volts.

Q: Switch only - No current overload protection provided.
