Description

Order No.: 3TH42620LF8 3TH4262-0LF8 Contactor relay, 62E, DIN EN 50011, for railway applications 6 NO+2 NC, screw terminal Operating range 0.7…1.25xUS connected to varistor 100 V DC

Overview Standards

IEC/EN 60947‑4‑1

The contactor relays are finger-safe according to IEC 60529. Terminal covers may have to be fitted onto the connecting bars, depending on the configuration with other devices.

Ambient temperature
The permissible ambient temperature for operation of the contactors (across the full coil operating range) is -50 to +70 °C. Uninterrupted duty at temperatures < -25 °C and > +55 °C reduces the mechanical endurance, the current carrying capacity of the conducting paths and the switching frequency.

A clearance of 10 mm is required for side-by-side mounting at ambient temperatures >55 °C. There is no need to reduce the technical specifications.

Application

For operation in installations which are subject both to considerable variations in the control voltage and to high ambient temperatures, e.g. in railway applications.

Control and auxiliary circuits
The solenoid coils of the contactor relays have an extended coil operating range from 0.7 to 1.25 x Us and are fitted as standard with varistors to provide protection against overvoltage. The opening delay is consequently 2 to 5 ms longer than for standard contactors.
