Acme Finger-Guard FS series control transformers cross to Micron GlobalTRAN by VA and group. FS-2-100 (FS2100, 100 VA, 230 x 460 V to 115 V) crosses to Micron B100-2003-GA. Current Acme numbers drop the dashes, so FS-2-100 and FS2100 are the same part. Find the group digit after FS, then read across at the same VA.
Both lines are finger-safe and CE marked. For Acme TA-2, TA-69, TA-83 and ET numbers, use the Acme cross.

Source: Micron Industries cross reference for the Acme Finger/Guard (FS) series, from the Micron LVGP and control transformer cross reference file (2016 edition). Micron GlobalTRAN units are CE marked in accordance with the CB Scheme and IEC 61558. GAF and GAH suffixes add factory options; we confirm the exact suffix and fusing on every quote. 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 Acme FS number
FS is the Acme Finger/Guard control transformer. The digit after FS is the voltage group: 1 is 120 x 240 V to 24 V, 2 is 230 x 460 V to 115 V, 3 is the universal multi-tap unit. The last digits are the VA. FS-2-250 (FS2250) is 250 VA, 230 x 460 V to 115 V, and crosses to Micron B250-2006-GAF.
