Product details

It carries a TM240 thermal-magnetic release — that's the fixed-trip version, not adjustable — so what you see on the nameplate is what you get for overload and short-circuit protection. The interrupting ratings are substantial: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V, which means it can handle serious fault currents on the secondary side of a transformer or a large motor branch circuit without upstream coordination headaches.

At 76.2 mm wide, 130 mm tall, and 70 mm deep, this MCCB fits the standard SENTRON 3VA footprint — it'll drop into a panel that was laid out for a 3VA1 frame without rewiring the bus bars. Operating temperature spans -25 °C to 70 °C, with full 125 A current up to 50 °C; above that it derates to 112.5 A at 70 °C. That matters if this breaker lives near a hot transformer or in a non-climate-controlled enclosure out in the plant.

Auxiliaries and releases

That's handy for a PLC input that needs to distinguish a manual open from a trip. A trip indicator on the front tells you at a glance whether the breaker opened on overload or short circuit.

Frequently asked questions

Where can I buy the 3VA1112-4EF36-0DH0?

This MCCB is sourced and quoted to order through independent distribution. Availability and current pricing are confirmed at quote time against an RFQ.

What is the interrupting capacity of this breaker at 415 V?

The 3VA1112-4EF36-0DH0 is rated for 75.6 kA at 415 V, which covers most industrial secondary-side fault scenarios.

Does this MCCB include an undervoltage release?

Yes, the 3VA1112-4EF36-0DH0 ships with an undervoltage release (UVR) integrated. It trips the breaker if control voltage drops below the dropout threshold.
