Time Delay Control Switch Relay (TD-CSR) by Electroswitch


A new Time Delay Control Switch Relay (TD-CSR) from Electroswitch provides a safe 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 an unmatched measure of safety against arc flash danger. Once a local trip or close is initiated, the 10-sec 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 secs to activate the 10-sec delay. No special wiring is required for installation.
