Electroswitch闭锁继电器Series 24 CSR产品介绍：
Electroswitch Control Switch Relays (CSR) combine the function of a control switch with a
remote controlled solenoid allowing one device to do both the manual and supervisory control
function in the control of power circuit breakers. They eliminate the need to redesign substations
for redundant separate relays when manual substations convert to supervisory control.
CSRs provide manual or electric control switch operation by supervisory control. The CSR
looks, acts, and feels identical to a control switch.
Note: The Series 24 CSR Class 1E utility products comply with the following Nuclear
Standards: ANSI/IEEE C37.90, ANSI/IEEE C37.90.01, ANSI/IEEE C37.98, ANSI/IEEE
C37.105, ANSI/IEEE 323, ANSI/IEEE 344, ANSI/ASME NQA -1.

Electroswitch闭锁继电器Series 24 CSR产品操作：
Basic Circuit Operation
The control of the CSR Control Switch Relay for electric operation requires no special wiring. It
only requires two contacts (S1 and S2) to command the CSR to either the TRIP or CLOSE
position. Low level contacts (rated 1 ampere) may be used since S1 and S2 do not control
the rotary drive solenoid directly.
The standard station control bus voltage is used on all three circuits. The device, when shown
in the following figures is in the vertical NORMAL position. The CSR coil form shown on the
figures represents the rotary solenoid that drives the CSR. Its operation is further described
later. LS1 is a linear solenoid within the device that changes the sense of direction of the CSR
from left (TRIP) to right (CLOSE). The contacts shown as CSR are contacts within the device.
Other components are shown by conventional designations.
Mechanical Target
When the CSR Switch handle is turned, a mechanical target contained in the nameplate is
turned as well (GREEN for TRIP, RED for CLOSE). The target remains latched when the handle
returns to normal position and always shows the last active position.
