Siemens Shunt Release – 5ST3030 (110…415 V AC/DC)
The Siemens 5ST3030 is a SENTRON 5ST3 series shunt
release (shunt trip coil) designed for remote tripping of miniature
circuit breakers (MCBs) such as 5SL5, 5SL7, 5SY, 5SP4, 5SV, 5SU1, and
5SM2 series. It enables the breaker to be switched OFF electrically from
a remote control signal, improving safety and automation in electrical
distribution systems.
It is widely used in industrial control panels, fire
safety systems, emergency shutdown circuits, BMS/SCADA systems, and automation
panels, where remote disconnection of circuits is required.
