5ST3015 SIEMENS

The 5ST3015 auxiliary current switch from Siemens is a low-power device designed to enhance the functionality of your circuit protection system. Specifically engineered for seamless integration with miniature circuit breakers (MCBs) 5SL, 5SY, and 5SP, this auxiliary switch provides added control and monitoring capabilities. It is also compatible with incorporated switches 5TL1, residual current circuit breakers with overcurrent protection (RCBOs) 5SU1, and residual current devices (RCDs) 5SV. Featuring two normally closed (2 NC) contacts, the 5ST3015 enables remote indication of the MCB's switching status, allowing for prompt response to any changes in the circuit. When used with the 5SU1, a handle coupler 5ST3805-1 is required to ensure proper mechanical connection. This auxiliary switch is ideal for applications where remote monitoring and control of circuit breaker status are essential. Its compact design and easy installation make it a valuable addition to any electrical panel. By providing real-time feedback on circuit breaker operation, the 5ST3015 helps to improve system reliability and prevent downtime. This device enhances safety and efficiency in electrical installations.
