ZZZ-Transtector DR DIN-Rail AC Surge Protectors (SPDs)

Transtector DR DIN-Rail AC Surge Protectors (SPDs) are DIN-rail devices that use Silicon Avalanche Suppression Diode (SASD) technology to protect critical equipment powered by a 120VAC single-phase electrical service. These Transtector UL 94V-0 devices provide effective protection against electrical transients generated by external lightning events and internal switching events. The DR DIN-Rail SPDs support long-term system reliability by safely shunting high amounts of transient energy while maintaining a very low clamping voltage.
