The relays referenced here are obsolete and no longer in production. They have been superseded by the improved series 414A,
414B and 414C units covered by this instruction book. The information that follows is a guide to these older units, especially
in the event you are replacing one with the newer relay.
Drawout circuit boards of the same catalog number are interchangeable. Also units with catalog numbers of the form
214xxxx2 may replace units with the same catalog number of the form 214xxxxl (hand-reset units), where all digits except
the last are identical. Similarly, units of the form 214xxxx3 may replace units of the form 214xxxx0 (self-reset units). A unit
is identified by the catalog number stamped on the front panel and the serial number stamped on the bottom side of the
drawout circuit board. The major difference between the 214xxxx0, 214xxxxl series and the 214xxxx3, 214xxxx2 series unit
is that the latter models use hermetically sealed output trip contacts.
CATALOG SERIES 414AOOx6. 414BOOx6. 414COOx6
The 414A, 414B and 414C series units with catalog numbers ending with the digit "6" have been designed to provide a field
selectable link for changing the output contacts to either "self-reset" or "manually reset". Earlier models had to be purchased
with preselected output contact modes.
Drawout circuit boards are not interchangeable between the 414xxxx2,3 or the 414xxxx6 series. However, the rear terminal
connections are the same for all three series, therefore, the entire relay including the case assembly may be replaced with no
change in the external wiring.

Note: Units rated for 250 Vdc control are supplied with a 8200 ohm, 25 watt resistor connected to terminals
14 and 15. This resistor must be connected to these rear terminals for proper relay operation.
