Product details

Thermal derating — the real-world current curve

At 55 °C it starts to step down: 49 A, then 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. The TM210 release has an adjustable Ir of 50 A (fixed at max) and an instantaneous Ii fixed at 500 A, so it's a line-protection breaker, not a motor-protection piece with adjustable overloads.

The breaker measures 25.4 mm wide (1 inch), 130 mm tall (5.1 inches), and 70 mm deep (2.8 inches). That 1-pole width means it snaps into a standard DIN-rail or panel-mount footprint alongside other SENTRON 3VA units. The 4.9 W maximum power loss is low enough that thermal stacking in a multi-pole group isn't a concern in a ventilated enclosure.

Frequently asked questions

Where can I buy 3VA1150-5ED12-0AA0 and how is it quoted?

We source and quote this part to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock or price figures are published here.

What is the interrupting capacity of 3VA1150-5ED12-0AA0 at different voltages?

The interrupting capacity is 121 kA at 240 VAC and 9 kA at 415 VAC. The voltage class you're protecting into determines the fault-clearing headroom.

What is the thermal derating curve for this MCCB?

It holds 50 A from 40 °C to 50 °C, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. Plan for the drop if your panel runs hot.

Will 3VA1150-5ED12-0AA0 drop into a panel specified for 3VA1110-5EE32-0JA0?

Both are 1-pole SENTRON 3VA MCCBs with the same physical footprint (25.4 mm wide), so mechanical fit should be identical. However, verify the specific ratings — interrupting capacity, release type, and current settings — differ between order codes.
