Date Code 20151029 Protection Manual SEL-411L Relay
Introduction and Specifications
Models and Options
Thermal Overload Modeling. Use the relay with the SEL-2600A RTD
Module for dynamic overload protection using SEL
OGIC control
equations. For more information, see SEL Application Guide

OGIC Equations.
Bay Control. The relay provides bay control functionality with status
indication and control of as many as ten disconnects. The relay
features control for as many as two breakers and status indication of as
many as three breakers. Numerous predefined user-selectable mimic
displays are available; the selected mimic is displayed on the front-
panel screen in one-line diagram format. The one-line diagram
includes user-configurable labels for disconnect switches, breakers,
bay name, and display for as many as six analog quantities. The relay
features SEL
OGIC programmable local control supervision of breaker
and disconnect switch operations.
Alias Settings. Use as many as 200 aliases to rename any digital or analog
quantity in the relay. The aliases are now available for use in
customized programming, making the initial programming and
maintenance much easier.
Models and Options
Consider the following options when ordering and configuring the relay.
