Siemens relay contactor 3RH1911 3RT1916 3RT10
Siemens relay contactor 3RH1911 3RT1916 3RT10
This is a Siemens Coupling Relay and Contactor assembly. The relay is model 3RH1911-2FA31; the contactor is model 3RT1916. Features of the 3RT10 series (from the Siemens website):
The SIRIUS coupling relays to switch motors and auxiliary and control circuits have been especially designed to operate with electronic control systems. The contactors distinguish themselves as a result of their low power drain and the wide operating range of the solenoids.The high contact reliability of the auxiliary contacts guarantees that there are no fault signals even at low switching powers. Sensitive output stages are protected against switching overvoltages of the coil using an interated sure suppressor.
Features of the 3RH family (from the Siemens website):
Contactor relays are switching devices for control and auxiliary circuits and are used to control, provide signals and interlock switching devices and switchgear panels. It goes without saying that the 3RH1 SIRIUS contactor relays have connection designations in compliance with the standard and use a connection system which is both time and cost saving fulfilling the requirements from the field. The 3RH1 contactor relays and the size S00 motor contactors are the same size and have the same optical design; this represents a significant advantage, especially when it comes to accessories. They are designed for AC or DC operation and are available with screw or spring-loaded technology. The basic version of the contactor relays has 4 poles but this can be extended up to 8 poles using auxiliary contact blocks which can be snapped-on
