Product details

Siemens 3VM1225-4EE32-0AA0 — SENTRON MCCB, 250 A, Line Protection

It carries a maximum of 2 500 A and delivers a breaking capacity of 121 kA at 240 V AC, 76 kA at 415 V AC, 53 kA at 440 V AC, and 17 kA at 500 V AC — figures that tell you the fault current it can safely interrupt at each voltage level without upstream cascading. Current rating holds at 250 A up to 50 °C ambient, then derates to 243.3 A at 55 °C, 236.5 A at 60 °C, 229.8 A at 65 °C, and 223 A at 70 °C. Dimensions: 70 mm deep, 105 mm wide, 158 mm high.

Frequently asked questions

How do I get current pricing and availability for 3VM1225-4EE32-0AA0?

The 3VM1225-4EE32-0AA0 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commercial response.

What is the breaking capacity of 3VM1225-4EE32-0AA0 at different voltages?

Breaking capacity is 121 kA at 240 V AC, 76 kA at 415 V AC, 53 kA at 440 V AC, and 17 kA at 500 V AC. These are the maximum fault currents the breaker can safely interrupt at each voltage level.

Will 3VM1225-4EE32-0AA0 drop into a panel specified around 3VA1110-5ED32-0AA0 without rewiring?

Not directly — the 3VM1225-4EE32-0AA0 is a 250 A frame with a TM220 release, while the 3VA1110-5ED32-0AA0 is a different frame class and trip rating. Panel cutouts, bus bar spacing, and lug sizes differ between the 3VM and 3VA series. A physical fit check and coordination study are needed before substitution.
