Circuit A has a factory adjustable time delay that holds the CSR in the commanded position for
1 to 3 sec. The command contact closure time should be greater than 100 msec and less than
the time delay setting (to avoid pumping). This circuit is not recommended for applications
where the SCADA timing sequence is greater than three seconds as it will cause pumping.

Series 24 CSR ORDERING INFORMATION
The circuit breaker control switch relays
include an engraved nameplate, mechanical
target, and pistol-grip handle. Circuits 50, 52
and 58 also have a Turn-To-Latch position.
Also included are the control circuits previously
explained.
CSR Control Switch Relays have the same
flexibility of design as the Series 24 line of
Instrument and Control Switches and are
available with all the different contact
configurations expected from this type of
switch. Refer to switch section for details.
