Product details

The Siemens 3VA1112-5ED32-0KA0 is a SENTRON 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current Iu of 125 A at 40 °C and an insulation voltage Ui of 800 V. Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V — numbers that matter when coordinating downstream faults without cascading upstream.

The 125 A continuous rating holds steady up to 50 °C; above that it derates to 117.5 A at 60 °C and 112.5 A at 70 °C — check your enclosure ambient before sizing.

Frequently asked questions

Where can I buy 3VA1112-5ED32-0KA0 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at quote time.

Will 3VA1112-5ED32-0KA0 drop into a panel that was specified around 3VA1112-5EF32-0CA0 without rewiring?

Both are 3-pole 125 A MCCBs on the same 3VA1112 frame, so the physical footprint — 76.2 mm wide, 130 mm tall, 70 mm deep — is identical. The key difference is the release: the -5ED32-0KA0 uses a TM210 thermal-magnetic release with a shunt trip, while the -5EF32-0CA0 carries a different release variant. Verify the control wiring for the shunt trip matches your panel's auxiliary circuit; the line and load lugs are in the same positions.

What compliance documentation does this brand provide for 3VA1112-5ED32-0KA0?

The SENTRON series is typically supplied with a CE declaration of conformity and UL/CSA listing documentation. Specific certificates (RoHS, REACH) are available from the manufacturer's support portal using the order code.
