Its compact design allows for easy installation alongside existing protective devices, while the high-quality materials ensure long-term stability and consistent contact switching under various operating conditions.
Suitable for
Monitoring the open or closed status of circuit breakers
Integration into industrial electrical distribution panels
Commercial building automation and power management systems
Remote signaling of electrical protection device states
When it may not be suitable
This device is specifically designed for use with compatible Siemens circuit breakers and may not be compatible with circuit breakers from other manufacturers or different series. It is not intended for direct power switching of high-load circuits, as it is strictly an auxiliary signaling component.
Key specifications
Contact configuration: 1NO (Normally Open) + 1NC (Normally Closed)
Color: Grey
Application: Status signaling for circuit breakers
How to use
The Siemens 5ST3010 auxiliary switch is designed to be mounted directly onto the side of a compatible circuit breaker. Before installation, ensure that the main power supply to the distribution panel is disconnected to prevent electrical hazards. Align the switch with the mounting interface of the circuit breaker and snap it into place according to the manufacturer's mechanical guidelines. Once physically secured, connect the signaling wires to the appropriate terminals on the switch to integrate it into your monitoring or control circuit.
What to consider before purchase
Verify compatibility with your specific circuit breaker model
Ensure the installation space within the distribution panel is sufficient
Confirm that the signaling voltage and current requirements match your control system
Usage recommendations: Always perform a functional test after installation to ensure the auxiliary switch correctly reflects the status of the circuit breaker. Periodically inspect the connections to maintain reliable signaling performance.
