ОПИСАНИЕ ПРОДУКТА
SIEMENS 5ST3053 - Auxiliary Switch
This device is an auxiliary switch designed for integration with SIEMENS SENTRON modular protection devices, including Miniature Circuit Breakers (MCBs), Residual Current Devices (RCDs), and Residual Current Operated Circuit Breakers with Overcurrent Protection (RCBOs). It provides remote status indication of the main device's switching position (ON/OFF or tripped state) for signaling and control applications within industrial automation and building management systems. Its primary function is to enable supervisory control and data acquisition (SCADA) integration or local panel indication.
