I2R Indoor DIN-Rail DC Surge Protectors (SPDs)

Transtector I2R Indoor DIN-Rail DC Surge Protectors (SPDs) use SASD, MOV, or GDT technology to protect critical equipment that operates on a 48VDC electrical service. These Transtector DIN-rail-style SPDs include visual suppression status indicators, dry contact remote annunciation terminals, and replaceable suppression and fuse modules. The I2R Indoor DC series provides effective protection against transients generated by lightning and internal switching events. The SPDs support long-term system reliability by safely shunting high amounts of transient energy while maintaining a very low clamping voltage.
