Older Hevi-Duty Type SBE control transformers with a form letter after the dash cross to Micron by VA and form. E105-A (100 VA, 230/460/575 V to 115/95 V) crosses to Micron B100BTW37XX. E105-D (100 VA, 240 x 480 V to 24 V) crosses to B100PU7JK. The code before the dash is the VA. The letter after the dash is the voltage form. Find your form, then read across.
Numbers with no dash and no letter (E105, E550) and the newer Sola/Hevi-Duty numbers are on the Sola/Hevi-Duty cross. E105 crosses to Micron B100BTZ13JK.

Micron Group F: 208/277 V primary, 120 V secondary. Micron MBT13XK (208/230/460 V primary, 115 V secondary) also fits a 208 V line.
Source: Micron Industries control transformer cross reference for Hevi-Duty Type SBE, SMT and SZO (replaced by EGS Sola/Hevi-Duty), March 2018. Micron units through 750 VA are 105°C construction with provision for 13/32 x 1-1/2 in secondary fusing. The sheet prints some EconoTRAN numbers with a letter O (EF1KOBTWZ37); the Micron numbers use a zero. Form U (208/240/277 V primary, 120 V secondary) has no direct Micron standard; depending on your line voltage, Micron MBT13XK (208/230/460 V to 115 V), MBT713XK (208/230/460 V to 24/115 V) or MQ15XK (208/277 V to 120 V) can substitute. Send the number and we pick it with you. Linked Micron numbers open the part we list at the same VA and voltage. Our listing can carry an added suffix letter (for example B150BTZ13JKF); we confirm the exact suffix on every quote.
How to read an old Hevi-Duty number
Type SBE numbers start with E and a VA code: E060 = 50 VA, E095 = 75 VA, E105 = 100 VA, E180 = 150 VA, E225 = 200 VA, E275 = 250 VA, E320 = 300 VA, E380 = 350 VA, E550 = 500 VA, E850 = 750 VA, E1100 = 1 kVA. Type SZO uses a Y and the real VA (Y1500 = 1.5 kVA). The letter after the dash is the form: A, B, C, D, E, N, P or U. Type SMT uses a T and the VA in every form; the sheet says the SMT units interchange with Micron in all forms above. E550-C is 500 VA, 600 V to 120 V, and crosses to Micron B500WZ13XK.
