Micron Transformers
Part number module
ImperviTRAN, ValuTRAN,
EconoTRAN
• All ImperviTRAN P/Ns begin with “B”
– B050BTZ13JK
• All obsolete ValuTRAN P/Ns begin with “V”
– VF1K0BTZ13JK
• All obsolete EconoTRAN P/Ns begin with “E”
– EF1K0BTZ13
GlobalTRAN
• GlobalTRAN is built in ImperviTRAN
construction.
• All GlobalTRAN P/Ns end in “GA,GAF or
GAH”
– B050-2001-GA
– B150-2004-GAF
– B1K0-2008-GAH
Frequency
• ImperviTRAN designs are rated at 50/60 Hertz
(Hz).
• A 50Hz rated device can operate at 60Hz but a
60Hz device can’t operate at 50Hz.
– A device can always operate at a frequency higher
than nameplate.
• Some P/Ns include an “F” or “N” after the
initial letter.
– VF1K0BTZ13JK
– BN1K0BTZ13
– HN1K5G1519P
• The “F” = 50/60Hz.
• The “N” = 60Hz.
Exceptions
• P/Ns that date back before 1983
– May include a letter as the 2nd or 3rd character. This
identified the customer.
– BRQX040JCBXT7-50
– May include an “X” as the 2nd – 4th character. This
identified special construction.
– BX100MBT13
– BRQX040JCBXT7-50
Temperature Class
• An ending “F” denotes Class 130°C.
• B150BTZ13JKF
– Internally, Micron may replace with a leading “M”.
• M150BTZ13JK
• An ending “H” denotes Class 180°C.
• B1K5BTZ13JKH
– Internally, Micron may replace with a leading “N”.
• N1K5BTZ13JK
VA/KVA
• VA = Volts X Amps
• KVA = VA X 1000
• The numbers following the initial letter in the P/N =
VA size.

Primary Voltages
• The letters following the VA size = primary
voltage.

B = 230
L = 120
M = 208
Q = 277
P = 240
R = 380
T = 460
U = 480
W = 575
• A “Z” as the last letter = transformer can
handle a voltage range  5% of nominal
voltage (triple rated).

• 220/230/240, 440/460/480, 550/575/600
Exceptions
• The “Z” is deleted on triple rated P/Ns that would be
longer than 12 characters.
– B100MBT713XK
• All voltage reference is deleted from serialized P/Ns.
– B150-0484-1
– B150-2004-GAF
Secondary Voltages
• The numbers following the primary voltage =
secondary voltage
– B050LP7JK

covers
Jumpers
• Jumpers are used to connect terminals together.
Common uses are to derive either 230 or 460 from a
series/parallel wound device or sometimes to connect
fuse clips on the terminal block.
• Jumpers are denoted by a “J” as one or both of the
final 2 characters on the P/N.
– B050 BTZ13JK
– B050PU1519JJ
Exceptions
• Jumpers are included but not denoted in the
following P/N constructions:

• The letter “T” as one of the last 2 characters
denotes an optional Stack ‘n Store (J3) jumper.
– B100BTZ13TK
Secondary Fuse Clips
• Virtually all ImperviTRAN products include mounted
fuse clips for a 13/32 X 1-1/2 midget fuse on the
secondary side.
• This is denoted with a “K” at the end of the P/N, –1
on a serialized P/N & “F” on GlobalTRAN.

B050MQ15XK
B050-0482-1
B050-2001-GF
• Mounted fuse clips for ¼ X 1¼ or 9/16 X 2 type
secondary fuses can be ordered by substituting the
“K” with the following letter:
– Q = ¼ X 1¼
– M = 9/16 X 2
B100BTZ13JQ
B100BTZ13JM
• A “-3” at the end of a serialized P/N= no fusing
capability.
Primary Fuse Blocks
• Class ‘CC’ style & midget style fuse blocks can be
ordered as a factory installed option on
ImperviTRAN & ValuTRAN.
• The letter “R” as the next to last character = a class
‘CC’ fuse block.
– B100BTZ13RB
• The letter “N” as the next to last character = a midget
style fuse block.
– B100BTZ13NB
• A “–8” on a serialized P/N = class ‘CC’ fuse block.
– B100-0483-8
• The letter “K” at the end of a GlobalTRAN P/N =
class ‘CC’ fuse block.
– B100-2003-GK
• The letter “G” at the end of a GlobalTRAN P/N when
secondary fusing is also ordered = class ‘CC’ fuse
block.
– B100-2003-GG
Exceptions
• P/Ns dating before 1983
– Will not include characters for jumpers or fuse clips
(although installed).
– B100BTZ13
– May include a customer identifier after the secondary
voltage identifier.
– BX050ER7-FE
– May include an identifier calling out a design feature, ie:
CT = Center Tap
