Description

Setra’s Model CSS solid-core current switches provide a cost
effective solution for real-time monitoring of motor status
in common HVAC applications. The CSS is available with
fixed or adjustable trip set-point values alerting the user to
over or under current situations in the application, with trip
points as low as 0.25 A up to 135 A. The Model CSS’s design
utilizes magnetic induction current sensing technology
allowing the CSS switches to accurately operate over a
wide range of environmental conditions, without the need
for an additional power supply. The current switch is available
with a snap-on power relay designed to start or stop
AC motors during tripped set-point conditions, minimizing
service time in the field.
