SR469-P1-HI-A20-E Multilin 469 large motors

Product description

The Multilin™ 469 Motor Protection System, a member of the SR family of relays, provides protection,

control, simplified configuration and advanced communications in a cost effective industry leading draw-out

construction. Designed for medium voltage motors, the 469 delivers advanced protection with customizable

overload curves and single CT differential protection for added flexibility. The 469 also provides simplified

configuration using the Motor Settings Auto-Configurator, providing a quick and easy set-up of motor parameters.

Coupled with advanced protection and diagnostics, the 469 provides users the flexibility of multiple

communication protocols allowing integration into new and existing control networks.

Applications
• Protection and Management of three phase medium and large horsepower motors and driven
equipment, including high inertia, two speed and reduced-voltage start motors

Overload Curves
The curves can take one of three formats: standard, custom, or voltage dependent. For all
curve styles, the 469 retains thermal memory in a thermal capacity used register which
is updated every 0.1 second. The overload pickup determines where the running overload curve begins.
The 469 standard overload curves are of standard shape with a multiplier value of 1 to 15.
The voltage dependent overload curves are used in high inertia load applications, where motor acceleration time can actually exceed
the safe stall time and motor thermal limits.
During motor acceleration, the programmed thermal overload curve is dynamically adjusted
with reference to the system voltage level. The selection of the overload curve type and the
shape is based on motor thermal limit curves provided by motor vendor.
