Product details

Siemens 3VA1112-5EF32-0AG0 — SENTRON MCCB, 125 A, Line Protection

Breaking capacity — what the voltage-specific ratings mean for fault clearing

Breaking capacity is stated per voltage level: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. For a 415 V industrial panel fed from a transformer with a 100 kA prospective fault current, this breaker clears it. At 690 V the margin is tighter — 17 kA limits it to lower-fault installations.

Thermal derating — continuous current across ambient temperature

Above that it derates: 120 A at 55 °C, 117.5 A at 60 °C, 115 A at 65 °C, and 112.5 A at 70 °C. Plan the load at the actual ambient, not the nameplate.

The trip indicator flag is present — visible through the front cover, useful for troubleshooting without opening the panel door.

Frequently asked questions

How is 3VA1112-5EF32-0AG0 quoted and supplied?

This part is sourced through independent distribution and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time — no stock count or price is published here.

What is the closest functional second-source for 3VA1112-5EF32-0AG0?

The 3VA1112-5EF32-0CA0 is a peer variant in the same SENTRON 3VA series. The -0AG0 carries the TM240 release with line protection; the -0CA0 differs in its release or accessory configuration. Both share the same 125 A frame, 3-pole layout, and physical footprint — but verify the release type and auxiliary contact spec before substituting.

What is the depth of 3VA1112-5EF32-0AG0?

The depth is 70 mm. Width is 76.2 mm, height is 130 mm.

Will 3VA1112-5EF32-0AG0 drop into a panel designed for 3VA1112-5EF32-0CA0?

Yes — both share the same 3VA frame dimensions (76.2 mm wide, 130 mm tall, 70 mm deep) and 3-pole layout. The mounting footprint and bus-bar spacing are identical. The difference is in the release or auxiliary contact configuration, not the mechanical fit.
