Weymouth, MA — A new Time Delay Control Switch Relay (TD-CSR) from
Time-Delay, Arc-Flash-Control Safety Relay from Electroswitch
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 cost. 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 company’s 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 con- tact resistance for low-level control applications. Rugged, standard screw-type
terminals have a 30A/600V continu- ous-current rating. The TD-CSR
meets IEEE C37.90 series standards. Contact: Electroswitch, 180

Arc safety switch control.
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
