Benefits
The Siemens 5ST3031 shunt release enables a compatible protective device to be tripped remotely by applying the appropriate control voltage. This makes it useful where an electrical circuit needs to be disconnected from a remote location, such as through an emergency-stop, fire protection or other external control circuit.
The device occupies 1 modular width (18 mm), helping save space inside distribution boards and control panels. Siemens specifies compatibility with the 5SL4, 5SY, 5SP, 5SU1 and 5SV ranges, while the 5ST3805-1 handle coupler is required when combining it with a 5SU1 RCBO.
Before installation, always verify the exact compatible base device, control voltage, wiring arrangement and application requirements.
