Product details

125 A MCCB with 220 kA interrupting capacity — line protection for high-fault panels

The Siemens 3VA1112-6EF36-0AE0 is a SENTRON 3-pole molded case circuit breaker (MCCB) rated for 125 A continuous at 40 °C, with a thermal-magnetic TM240 release designed for line protection in distribution panels. Its interrupting capacity reaches 220 kA at 240 V, 154 kA at 415 V, and 75.6 kA at 440 V — figures that handle high available fault current without cascading upstream breakers.

Current derating and thermal profile

Continuous current holds at 125 A from 40 °C through 50 °C, then derates to 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C (–). The 70 mm depth, 76.2 mm width, and 130 mm height (–) match the standard 3VA1 DIN-rail footprint — panel cutouts and busbar spacing carry over from other 3-pole SENTRON breakers.

Frequently asked questions

What are the interrupting ratings for 3VA1112-6EF36-0AE0?

220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V (–). These are the maximum fault currents the breaker can safely interrupt at each voltage level.

Where can I buy 3VA1112-6EF36-0AE0?

This part 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 commitment.

What is the continuous current rating at elevated ambient temperatures?

125 A from 40 °C to 50 °C, then derated: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C (–).
