Date codes on NEMA Freedom/A200 series contactors

The date codes are typically configured with a "T" prefix and a week/year format. For example, if the date code is T1317, this would indicate the device was manufactured on the 13th week of 2017. There may be instances of a six-digit number in a yr/mo/day format, for example 170425. This would indicate a manufacturing date of April 25th, 2017.
