Product details

125 A MCCB with shunt trip — panel fit and breaking capacity

The Siemens 3VA1112-3EF36-0KA0 is a SENTRON 3-pole molded case circuit breaker rated 125 A continuous at 40 °C (derates to 114 A at 70 °C ambient). Its interrupting capacity reaches 75.6 kA at 240 V AC, 52.5 kA at 415 V, and 11.9 kA at 690 V — covering most low-voltage distribution and motor branch circuits in industrial panels. This unit includes a factory-installed shunt trip (STL) auxiliary release for remote tripping via a control signal — useful in emergency-stop chains or automated shutdown sequences.

At 240 V the breaker clears 75.6 kA symmetrical — enough for most service-entrance and sub-feed applications. At 415 V that drops to 52.5 kA, and at 690 V to 11.9 kA.

Thermal derating — real-world current capacity in a warm panel

Rated 125 A up to 50 °C without derating. Above that it drops: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, 114 A at 70 °C.

Frequently asked questions

Where can I buy 3VA1112-3EF36-0KA0 and how do I get a price?

Sourced to order through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is 3VA1112-3EF36-0KA0's listed depth (70 mm) on this component line?

The depth is 70 mm (2.76 in). Width is 76.2 mm (3 in), height is 130 mm (5.12 in). These dimensions match standard MCCB panel cutouts.

Will 3VA1112-3EF36-0KA0 drop into a panel that was specified around 3VA1110-5ED36-0AC0 without rewiring?

Both are 3-pole SENTRON MCCBs with similar dimensions (76.2 mm width, 70 mm depth), so the mechanical footprint is compatible. However, the 3VA1112-3EF36-0KA0 carries a 125 A TM240 release versus the lower-rated release on the 3VA1110-5ED36-0AC0 — verify that the conductor sizing and upstream protection match the 125 A rating before swapping.

What compliance documentation does this brand provide for 3VA1112-3EF36-0KA0 (RoHS, REACH, UL, IEC)?

As a Siemens SENTRON product, this MCCB carries CE marking for the European market and is designed to IEC 60947-2. RoHS and REACH compliance declarations are available from Siemens documentation. UL listing status should be confirmed against the specific UL file number for this order code.
