It provides visible isolation for a circuit — it is not a circuit breaker and carries no overload or short-circuit protection. Four auxiliary switches (form C / changeover contacts) report the main contact position back to a PLC or status lamp. This is a panel-mount device for a switchboard or distribution enclosure. The nut keeper kit simplifies mounting on a mounting plate or DIN rail adapter. The 4-pole configuration (3 phases + neutral) suits it for three-phase systems where the neutral must also be isolated. The undervoltage release coil draws continuously when energized; verify the control transformer is sized for the holding current.","metaTitle":"SENTRON 3VA1225-1AA42-0DE0 Switch Disconnector, 250A, 4-Pole","metaDescription":"SENTRON 3VA1225-1AA42-0DE0 switch disconnector, IEC frame 250, 4-pole, 250 A, undervoltage release 208-230 V AC, 4 aux switches.
