This is a straightforward overcurrent-only breaker for distribution or feeder duty.
Rated breaking capacity hits 187 kA at 240 V, 121 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V. The thermal-magnetic release holds 250 A flat from 40 °C through 50 °C, then derates to 243.3 A at 55 °C, 236.5 A at 60 °C, 229 A at 65 °C, and 223 A at 70 °C.
Dimensions: 105 mm wide, 158 mm tall, 70 mm deep. No separate aux kit to order.
Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
Rated continuous current 250 A, breaking capacity 187 kA at 240 V and 121 kA at 415 V, rated insulation voltage 800 V, TM240 thermal-magnetic release, 3 poles.
The 3VA1225-5EF32-0AH0 has a depth of 70 mm.
The 3VA1225-5EF32-0AH0 has a width of 105 mm.
Both are 3-pole SENTRON MCCBs on the same frame family, so the mounting footprint and bus-bar centers match. The 3VA1225-5EF32-0AH0 is a higher-current variant (250 A vs the 3VA1110's lower rating) with a different TM release; verify the load-side conductor sizing and fault-current coordination before swapping.
