Product details

Siemens 3VA1150-3EF36-0AF0 — SENTRON MCCB, 50 A, Line Protection

Three poles, rated 50 A continuously at 40 °C (derated to 45 A at 70 °C), with a TM240 thermal-magnetic release that handles overloads and short-circuits in one package. Interrupting capacity is voltage-dependent: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V and 690 V.

Panel Integration & Dimensions

Dimensions: 130 mm height, 76.2 mm width, 70 mm depth — fits most 600 V switchgear enclosures without re-drilling. The 3VA1 family shares the same mounting pattern across current ratings, so swapping a lower-rated unit for this 50 A version is a straight drop-in.

Frequently asked questions

Where can I buy 3VA1150-3EF36-0AF0?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.

What is the interrupting capacity of this MCCB?

75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V and 690 V.

Will 3VA1150-3EF36-0AF0 fit in a panel designed for 3VA1110-5EF32-0AM0?

Both are 3-pole SENTRON MCCBs in the same 3VA1 family with identical mounting footprint (130 x 76.2 x 70 mm) — a direct mechanical swap. The main difference is the trip unit: this one is a 50 A TM240 line-protection breaker, while the 3VA1110-5EF32-0AM0 is a 100 A unit with a different release. Verify the load rating before substitution.
