Product details

Siemens 3VA1050-3ED36-0KA0 — SENTRON MCCB with Shunt Trip

Interrupting capacity steps with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. That spread covers most low-voltage industrial distribution — 480/277 V and 400/230 V grids are well within the curve. The overcurrent release is the TM210 thermal-magnetic type, a fixed-trip design suited for feeder and branch-circuit protection where adjustable magnetic pickup isn't needed.

Three-pole construction, 76.2 mm wide (3 in), 130 mm tall (5.12 in), 70 mm deep (2.76 in). No trip indicator window, so visual status checking requires the handle position.

Frequently asked questions

How do I get current pricing and availability for 3VA1050-3ED36-0KA0?

Submit an RFQ through this listing. The part is sourced to order through independent distribution; pricing and availability are confirmed at quote time.

What is the interrupting capacity of 3VA1050-3ED36-0KA0 at 240 V?

75.6 kA at 240 V AC. At 415 V it's 52.5 kA, at 440 V it's 32 kA, and at 500 V or 690 V it's 7.5 kA.

Does 3VA1050-3ED36-0KA0 include a shunt trip?

Yes, it includes a shunt trip (STL) auxiliary release — a separate control voltage can trip the breaker open remotely. No undervoltage release or ground-fault monitoring is fitted.
