1–8 345 TRANSFORMER PROTECTION SYSTEM – INSTRUCTION MANUAL
345 ORDER CODES CHAPTER 1: INTRODUCTION
Empty chassis
The 345 protection relay chassis used with a drawout relay is available separately, for use
as a partial replacement or in test environments. Many features are supported by the
cards and ports within the chassis, as is reflected in the chassis order code.
NOTE:
The chassis order code and drawout relay order code must match exactly.
FAST PATH:
A drawout relay cannot be used in a chassis with different order code options.

Remote Module I/O
The remote RTD Module provides additional protection by monitoring the temperature of
key components in the equipment.
