A new Time Delay Control Switch Relay (TD-CSR) from Electroswitch provides a safe and effective means of mitigating arc flash danger in local circuit breaker operation by allowing for a manually initiated time-delayed trip or close. A flashing LED notifies the operator of the pending trip or close operation and serves as a warning to evacuate the arc flash area. By allowing an operator time to leave the room before the trip or close operation, the TD-CSR affords the operator the same safety from arc flash as a SCADA system — at a small fraction of the price.
Once a local trip or close is initiated, the 10-second delay allows an operator time to cancel the pending operation. To avoid any chance of an inadvertent operation, the control pushbuttons must be depressed for 4 continuous seconds to activate the 10-second delay. Other delay time options are available. The unit’s intuitive pushbutton design simplifies personnel training. No special wiring is required for installation.
The TD-CSR is available with the same reliable features and options as the field-proven Electroswitch Control Switch Relay. These features include a standard mechanical target (“flag”) to show the last operating position and an optional lighted nameplate. The nameplate includes local LED indication, a remote SCADA contact alarm, and a single or dual trip-coil monitoring option.
Reliable, self-cleaning, double-wiping contacts with silver or silver-alloy surfaces provide very low contact resistance for low-level control applications. Rugged, standard screw-type terminals have a 30A/600V continuous-current rating. The TD-CSR meets the same IEEE C37.90 series standards as all other Electroswitch relay products, confirmed by periodic in-house testing.
