It is a straightforward disconnect device — no overload or short-circuit protection built in, so it serves as a visible-break isolation point in a distribution panel, not a combined motor-protective device. The integrated undervoltage release (208-230 V AC, 50/60 Hz) provides automatic tripping on voltage loss, which is a common requirement for safety circuits or emergency-stop chains. Panel-mount disconnect for a 4-pole circuit, rated 250 A.","metaTitle":"Siemens 3VA1225-1AA42-0DF0 Switch Disconnector, 250A, 4-Pole","metaDescription":"Siemens 3VA1225-1AA42-0DF0 switch disconnector, 250A rated current, 4-pole, IEC frame 250.
