The Termitrab Complete family’s TTC-6P-4 four-wire pluggable surge protective devices (SPDs) protect against overvoltages on four conductors in a width of 6 mm, or 1.5 mm per conductor. The devices are designed for measurement and control applications, such as precise temperature and weight measurements, that are sensitive to impedance. They have been tested to UL 497B, including Class I, Div. 2 approval for hazardous locations. The SPDs provide mechanical signaling that displays the overload status of the protective devices without the need for additional auxiliary power. A status indicator shows the state of onsite surge protection equipment.
