Product description

The Siemens 5ST3010 is an auxiliary switch designed to provide additional signaling contacts for various Siemens miniature circuit breakers and residual current devices. This unit features a 1 Normally Open (NO) and 1 Normally Closed (NC) contact configuration, allowing it to signal the status (on/off/tripped) of the main protective device to a control system or monitoring panel.

This auxiliary switch is compatible with Siemens 5SL, 5SY, and 5SP miniature circuit breakers, as well as 5SU1 RCBOs and 5SV RCDs. It is designed for easy integration, clipping onto the side of the compatible breaker. For integration with 5SU1 RCBOs using a handle coupler, the 5ST3805-1 accessory is required.
