Benefits

The Siemens 5ST3010 adds a 1NO + 1NC auxiliary contact arrangement to compatible Siemens devices. This allows the operating status of a protective or switching device to be communicated to an external control, indication or monitoring circuit.

The combination of one normally open and one normally closed contact provides flexibility for different control and signalling requirements. For example, one contact can be used for an operating-status indication while the other can be incorporated into an interlocking or alarm circuit.

Its compact modular design makes it suitable for installation alongside compatible Siemens protective devices in distribution boards and industrial control panels.

For 5SU1 RCBO applications, always check the exact device version and required coupling accessories before installation.
