The Siemens 3LD4001-4DC30-0RC0 is a 3LD4 Voltmeter Selector Switch (VSS) designed for measuring different line and phase voltages using a single analogue voltmeter. It is part of the Siemens 3LD4 Control Switches range and is suitable for professional electrical metering and monitoring applications.
This model is a 6A, 7-position voltmeter selector switch with an OFF position, allowing selection of different voltage measurement points in three-phase electrical systems. The 7-position configuration is designed for measuring both line-to-line (L-L) and line-to-neutral (L-N) voltages through one analogue meter.
By using one voltmeter for multiple voltage measurements, the 3LD4001-4DC30-0RC0 can help reduce panel space, simplify instrumentation and provide convenient voltage monitoring for operators and maintenance personnel.
The Siemens 3LD4001-4DC30-0RC0 can be used in:
Siemens specifically identifies VSS applications in MCCs, PCCs, OEM equipment and metering panels.
The main advantage of the Voltmeter Selector Switch is that multiple voltage measurements can be performed using one analogue voltmeter, rather than requiring a separate meter for each measurement point. Siemens describes the VSS as a solution for measuring different line and phase voltages with a single analogue voltmeter.
The 7-position configuration provides flexibility for monitoring both line-to-line and line-to-neutral voltages, while the OFF position allows the measurement circuit to be disconnected when required.
The cam-operated rotary design provides sequential make-and-break switching as the selector is rotated between positions. This makes the switch suitable for conventional industrial metering and control-panel applications.
For replacement or new-panel installations, verify the metering circuit, required voltage-selection positions, current rating and wiring configuration before installation.
