3RH11401BB40 Datasheet, PDF (4/76 Pages) Siemens Semiconductor Group – 3RT10 motor contactors
3RT, 3RH, 3TB, 3TC, 3TH, 3TK Contactors for Special Applications
Contactors with Extended Tolerance 0.7 ... 1.25 x Us, for Railway Applications
3TC contactors for switching DC voltage, 2-pole
■ Overview
■ Application
EN 60947-4-1.
For requirements according to IEC 60077-1 and IEC 60077-2.
The contactors are finger-safe according to EN 50274
(exception: series resistor). Terminal covers may have to be
fitted onto the connecting bars, depending on the configuration
with other devices.
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.
■ Selection and ordering data
