CONTROL SWITCH RELAYS E 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 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.

Let us put over 50 years of know-how to work for you! 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.

This includes being subjected to transients on the control bus up to CIRCUIT SINGLE SINGLE RATING* RATING 3.5KV. Since the CSR is normally isolated from the bus, it will experience transients only if VOLTS CONTACT CONTACT (AMPS) (AMPS) they occur in the operating mode. This precludes the possibility of a detrimental, accumulating 12VDC – – 60 30 affect over the life of the unit. As such, no transient protection is needed with circuits B and C. – – 60 30 24VDC Circuit A with its voltage divider circuit does remain on the bus and therefore contains a bipolar 48VDC – – 60 30 diode, as previously explained, to clip the transients to an acceptable value. 3 3 60 30 125VDC 250VDC – – – – – – – – Because of the nature of the operation of the rotary solenoid, the CSR does generate tran- 600VDC 120VAC 20 20 60 30 sients that may be of interest to the user.
