Siemens S01EE4R3 U 240 is a shunt‑trip accessory for EH3 circuit breakers that enables remote tripping in safety‑critical control circuits. The coil is rated for 120–240 VAC (U 240), and energizing it trips the connected EH3 breaker to interrupt power and protect personnel and equipment. It mounts on compatible EH3 breakers and is used where a remote stop signal is required in industrial automation. This device provides a rapid shutdown pathway in fault conditions, reducing the need for local operator action.
