Source: Micron Industries control transformer cross reference for Siemens Energy and Automation Type MT, March 2018. Micron units through 750 VA are ImperviTRAN or ValuTRAN, 105°C construction, with 13/32 x 1-1/2 in secondary fuse clips where applicable. 1 kVA and up are EconoTRAN, 180°C. 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 a Siemens MT number
MT is the Siemens machine tool control transformer. The four digits are the VA (0100 is 100 VA, 1000 is 1 kVA). The last letter is the voltage. MT0250A is 250 VA, 230 x 460 V to 115 V. The Micron cross is B250BTZ13JK. Micron offers a class CC primary fuse block option through 750 VA. Tell us if you need fusing and we match it.
