SERIES 24 CSR
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 substa- tions 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 NuclearC37.105, ANSI/IEEE 323, ANSI/IEEE 344, ANSI/ASME NQA -1.
Standards: ANSI/IEEE C37.90, ANSI/IEEE C37.90.01, ANSI/IEEE C37.98, ANSI/IEEE

Let us put over 50 years of know-how to work for you! 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.
Basic Circuit Operation
The control of the CSR Control Switch Relay for electric operation requires no special wiring. It 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. in the following figures is in the vertical NORMAL position. The CSR coil form shown on the
