The Siemens 3LD41044DC200RC0 is an Instrumentation Selector Switch / Ammeter Selector Switch (ASS) from the Siemens 3LD4 series. It is designed for selecting and monitoring current from different phases through a single ammeter, making it useful for electrical metering and control panels.
This model is rated at 20A and is configured for line-current measurement with OFF. Siemens documentation describes the ASS as a selector used to obtain different phase-current readings using one analogue ammeter. The line-current-with-OFF version provides selection of the three phase currents with an OFF position.
The 3LD41044DC200RC0 is suitable for MCCs, PCCs, OEM equipment, metering panels and industrial electrical control systems where monitoring multiple phase currents with a single meter is required.
Siemens' product documentation identifies the ASS range as being available in 6A, 10A, 16A and 20A versions, with the line-current-with-OFF configuration intended for measuring three-phase currents.
The Siemens 3LD41044DC200RC0 can be considered for:
The main advantage of an Ammeter Selector Switch is that it allows different phase-current measurements to be selected using one analogue ammeter, reducing the need for separate meters for each phase. Siemens specifically describes this as a solution for obtaining different phase-current readouts through a single ammeter.
The line-current-with-OFF configuration is intended for selecting the current of different phases while providing an OFF position. This makes it useful in conventional three-phase metering arrangements in MCCs, PCCs and industrial panels.
The 20A rating makes this model suitable for applications where the selector switch's electrical rating matches the control or metering circuit requirements. Always verify the complete circuit design, meter connection and required selector-switch configuration before installation.
