The Tii SmartRCD is an EN61008 compliant self-testing, auto re-closing, electronically integrated RCD. This 2 pole unit is designed to directly replace existing RCDs to allow the end user to comply with BS7671 17th edition regulations regarding periodic testing. The unit is microcontroller based and can be custom programmed with a desired test schedule. The default test period is 90 days, eliminating the need for a competent person to attend and carry out the periodic test.
The SmartRCD is ideally suited to be housed in remote, hard to reach equipment or street furniture. The micro-controlled electronic device, unlike most traditional RCDs, is designed with robust immunity to noise, EMC, and start up currents only to react to real life fault conditions. In the event of a transient fault or nuisance trip caused by lightning or something similar, the SmartRCD will restore the AC mains contacts automatically, eliminating a costly truck roll.
Additional benefits: Master and Slave communication, allowing 2x30mA SmartRCDs to be installed in the same circuit. The master device will never trip before the slave device on a downstream fault occurring from the slave device. Any fault occurring upstream of the slave will trip the master device as per normal requirements.
