The order code includes an undervoltage release (24 V DC) and two auxiliary changeover switches, plus a nut keeper kit for the front terminals. This is a load-break switch for isolation and switching duty, sized for a 250 A circuit. The 250 A rating on the IEC frame 250 means this switch handles full-load current for a 250 A feeder or large motor circuit — it's a disconnect, not a protective device, so it sits downstream of a breaker or fuse. The 4-pole configuration (3 phases + neutral) suits three-phase distribution panels where neutral switching is required. The undervoltage release (24 V DC) drops the switch on loss of control voltage, typical for emergency-stop or undervoltage protection schemes.","metaTitle":"SENTRON 3VA1225-1AA42-0BB0 Switch Disconnector, 250 A, 4-pol","metaDescription":"SENTRON 3VA1225-1AA42-0BB0 switch disconnector, IEC frame 250, 4-pole, In=250 A, with undervoltage release 24 V DC and 2 auxiliary switches.
