Benefits
The Siemens 5ST3030 shunt release allows a compatible protective device to be tripped remotely when the appropriate external control voltage is applied. This makes it useful in installations where electrical circuits need to be disconnected through an external control, emergency-stop or shutdown signal.
Its 1 MW (18 mm) modular width helps save panel space, while compatibility with the 5SL4, 5SY, 5SP, 5SU1 and 5SV ranges provides flexibility for suitable SENTRON protection applications. For installation with a compatible 5SU1 RCBO, the 5ST3805-1 handle coupler is required.
Before installation, verify the compatible base device, control voltage, wiring arrangement and application requirements.
