Product details

The SENTRON 3VA1225-1AA42-0DE0 is a 4-pole switch disconnector on the IEC frame 250, rated at 250 A. 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.

Frequently asked questions

Where can I buy 3VA1225-1AA42-0DE0 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Submit an RFQ for current pricing and availability — both are confirmed at quote time.

What is the closest functional second-source — 5SQ2270-2YA04?

The 5SQ2270-2YA04 is a 2-pole miniature circuit breaker (MCB) from the SENTRON 5SQ series, rated 4 A with C-curve trip characteristic. It is not a functional second-source for the 3VA1225-1AA42-0DE0, which is a 250 A, 4-pole switch disconnector without overcurrent protection. The two parts serve completely different roles in a panel.

What compliance documentation does this brand provide for 3VA1225-1AA42-0DE0?

As a Siemens SENTRON product, the 3VA1225-1AA42-0DE0 is manufactured under IEC standards for switch disconnectors. Standard documentation includes a CE declaration of conformity and the manufacturer's datasheet. RoHS and REACH compliance declarations are typically available from Siemens upon request.
