Product details

The Siemens SENTRON 3VA1225-1AA32-0KA0 is a 3-pole switch disconnector in the 3VA1 IEC frame 250 platform, rated for 250 A continuous current (Iu) with a maximum AC operational voltage of 690 V and DC operational voltage of 500 V. Connection to the main circuit is via busbar on front terminals.

The 3VA1225-1AA32-0KA0 occupies a 105 mm wide, 70 mm deep, 158 mm high footprint on the panel backplate. It is designed for busbar connection at the front terminals, which suits distribution blocks or panel-internal bus runs. No auxiliary contacts are fitted (0 CO contacts), and no undervoltage release is present; the only integrated release is the shunt trip.

Frequently asked questions

What is the 3VA1225-1AA32-0KA0 used for?

It is a switch disconnector — a manually or remotely operated load-break switch for isolating a 3-phase circuit. It does not provide overload or short-circuit protection; it is intended for applications where disconnection is needed but protection is handled upstream or by a separate device.

What are the key ratings of 3VA1225-1AA32-0KA0?

Rated continuous current Iu is 250 A. Maximum AC operational voltage is 690 V (50/60 Hz), maximum DC operational voltage is 500 V. The shunt trip coil is rated 220-250 V DC or 208-277 V AC.

Where can I buy 3VA1225-1AA32-0KA0?

This part is available through independent industrial-automation distribution. It is quoted to order against an RFQ; current pricing and availability are confirmed at quote time.

Will 3VA1225-1AA32-0KA0 drop into a panel specified around 3VA1110-5EE32-0JA0?

No — the 3VA1110-5EE32-0JA0 is a 100 A molded-case circuit breaker on a 76.2 mm wide frame, while this part is a 250 A switch disconnector on a 105 mm wide frame. The footprint, busbar connection, and function are different; panel rework would be required.
