Control switch relay provides manual and supervisory control

The Series 24 Control Switch Relay (CSR) from Electroswitch provides both manual and supervisory control of power circuit breakers.  The unit's blade-and-terminal construction and simple stacking procedures allow up to two independent contacts in the same deck.  Custom contacting is available.  Contact ratings are 60 amps for one minute and 30 amps continuous, at up to 600 VAC.  A built-in bipolar diode enables the unit to withstand transients on the control bus up to 3.5 KV.

Configurable for various power industry applications, the Series 24 CSR combines the functions of a control switch and a remote-controlled solenoid — no special wiring required.  With three basic circuits, multiple-voltage capability, and a choice of contact configurations, the unit allows the automation of virtually any breaker control switch function.  When a manual substation is converted to supervisory control, the manual Series 24 CSR can be directly retrofitted into a SCADA-compatible breaker control switch, replacing interposing relays and associated wiring.

The Series 24 CSR is available with a SCADA disable function.  Pushing in the handle of this model disables remote operation, allowing only local/manual control so that testing or service can be performed safely.  Target flag agreement is always true, regardless of manual or electric trip, in either the remote or local mode.  The target remains latched when the handle returns to normal position and always shows the last active position.  In addition, this model provides push-activated N/O and N/C contacts (with electrical connections) for customer use as SCADA feedback of status indication.

Series 24 CSRs comply with relevant ANSI/IEEE, UL, and CSA standards.  Prices start at $500 with delivery quoted at two weeks ARO.
