The Shallco Series 26 Control Switch Relay (CSR- ANSI Device 69 or 52CS) is an electrically operated control switch for both manual and remote operation of industrial and utility power circuit breakers (ANSI Device 52)
The Circuit Breaker Control Switch (CSR) typically has two sets of momentary contacts –Trip Contacts and Close contacts with a spring return of the switch shaft to the normal (center) position after operation of the breaker; however, thee CSR can be configured just as the standard manual type control switches along contacts that depict that an operation has been performed commonly referred to as slip contacts. These contacts latch either after the Trip function or the Close function. These usually provide indication to the operator that the state of the breaker has changed.
These Circuit Breaker Control Switch Relays (CSRs) have the same mechanical targets as the standard breaker controls switches (Red and Green and indicate the state of the breaker). CSRs can be supplied with a Lighted Panel that can be wired to indicate an event. SCADA monitoring circuits are inclusive in the lighted panel and can be used for numerous audio or lighted signal indications based on the circuit input.
The CSR can also be configured with Time Delay (TD) circuitry provide protection for ARC Blast. (See Time Delay Relay (TDR) For Arc Flash Protection)
