Product details

The Siemens 3VA1450-1AA42-0BJ0 is a 4-pole switch disconnector in the 3VA1 IEC frame 630 series, rated at In=500A. It comes without overload or short-circuit protection — it's a straight disconnect, not a breaker — and includes an undervoltage release (24 V DC) plus a nut keeper kit. The accessory complement adds two auxiliary switch changeover contacts (H) and one trip alarm switch changeover.

The undervoltage release (24 V DC) is wired as an accessory, so verify coil polarity and suppression before energizing.
