Delaying danger

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 and be outside the room during the trip or close operation, the TD-CSR provides safety against arc flash danger, the company said. 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 four 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 features and options as the company's Electroswitch Control Switch Relay, including 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.
