2) Check date codes of potentially affected product
To identify affected product on the carton or device, follow the guidance below:
RCBOs for singular installation
Date codes are constructed by a letter ‘F’ prefix followed by 4 x digits – the letter is irrelevant and the date
code reads year/week e.g. F1541 means year 2015, week40.
Date code range for devices:
F1531 – F1552, F1601 and F1602
Product in carton of 5 units
Date code label for affected
RCBOs will be in the range:
F1531-F1552
F1601-F1602
Individual products
Date code label for
affected RCBOs
will be in the
range:
F1531-F1552
F1601-F1602

RCBOs in Fully Populated Arrangements
Date codes are constructed by a letter ‘T’ prefix followed by 4 x digits – the letter is irrelevant and the date
code reads year/week e.g. T16 04 means year 2016, week 04.
Date code range for fully populated boards:
T1543 – T1552 and T1601-T1623
Products outside of the identified date codes are unaffected and should not be returned. .
This potential issues has been eliminated for all products shipped from 6 June 2016
RCBO’s shipped after this date, are also identifiable by the addition of the words 'by Honeywell’ under the
MK logo – please see below for indicative image;
Addition of 'by
