DINsafe - SDD3 Three Phase Surge Diverters
Novaris SDD DINsafe Surge Diverters offer powerful performance at domestic MSB and industrial DBs. The SDD diverters are housed in a DIN compliant, fail-safe metal enclosure. The SDD range incorporates electronic monitoring providing a colour coded LED indicator per phase. This makes monitoring fail-safe. When the LEDs are ON, the SPD is fully functional. If one or more of the phase LEDs is OFF either the backup fuse has ruptured, the power has failed or the thermal disconnect has tripped. Models equipped with external alarms reflect these conditions through an SPDT voltage free contact. Only electronic monitoring provides fail-safe status reporting.
