Old models 0351xM and 0351xJ have been superseded by models 0351xT and 0351xY,
respectively. This is due to improvements in Connectorized
®
SEL-351 Relays (plug-in connectors)
– see Section 2: Installation for more details. Unless otherwise noted, references to models
0351xT and 0351xY also apply to old models 0351xM and 0351xJ, respectively.
The model numbers are derived from the SEL-351 Relay ordering information sheet. The model
numbers in Table 1.1 are only the first part of an actual ordering number – enough to distinguish
one model type from another. The “x” field indicates the firmware version (see Table 1.2).
