Product details

Siemens 3VA1125-5EF36-0HC0 — SENTRON 25 A MCCB with TM240 Release

At 415 VAC it still holds 121 kA, dropping to 75.6 kA at 440 VAC and 17 kA at 690 VAC. That means the overload and short-circuit pickup are factory-set to the 25 A frame rating. For applications needing adjustable long-time, short-time, or ground-fault protection, this is not the variant; look to the electronic-release versions in the 3VA family. The trade-off is simplicity and reliability in a fixed-coordination panel.

At 55 °C it derates to 24 A, at 60 °C to 23.5 A, at 65 °C to 23 A, and at 70 °C to 22.5 A.

Integrated Auxiliary and Shunt Trip

Width 76.2 mm (3-inch pitch, standard for 3-pole MCCBs in the SENTRON frame), height 130 mm, depth 70 mm.

Frequently asked questions

Where can I buy 3VA1125-5EF36-0HC0 and what is the lead time?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm lead time.

What is the breaking capacity of 3VA1125-5EF36-0HC0 at different voltages?

187 kA at 240 VAC, 121 kA at 415 VAC, 75.6 kA at 440 VAC, and 17 kA at 690 VAC.

What overcurrent release does this MCCB use?

A fixed TM240 thermal-magnetic release — no interchangeable trip block, no electronic adjustment. Overload and short-circuit pickup are factory-set to the 25 A frame rating.

Does this breaker include auxiliary contacts or a shunt trip?

Yes, factory-fitted with 2 HQ auxiliary switches and a shunt trip release (STL). The integrated auxiliary trip assembly order code is 3VA9688-0BL30.
