3RT, 3RH, 3TB, 3TC, 3TH, 3TK Contactors for Special Applications
Contactors with Extended Tolerance 0.7 ... 1.25 x U_s, for Railway Applications
3TH4 contactor relays
■ Overview
■ Application
3TH4 contactor relays
EN 60947-4-1.
For requirements according to IEC 60077-1 and IEC 60077-2.
For operation in plants which are subject both to considerable
variations in the control voltage and to high ambient
temperatures, e.g. in railway applications.
The contactors are finger-safe according to EN 50274. Terminal
covers may have to be fitted onto the connecting bars,
depending on the configuration with other devices.
