Product details

The interrupting ratings are what make this breaker stand out: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V.

Above that it derates: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C.

That 76.2 mm width is a standard 3-pole MCCB footprint — it fits the same panel cutout and bus-bar spacing as other SENTRON 3VA 3-pole frames.

Auxiliary contacts and trip indication

The trip alarm switch changes state only when the breaker trips on a fault — useful for remote fault annunciation or a shunt-trip circuit. A trip indicator is also built into the front, so a walk-by inspection shows a tripped breaker without opening the panel door. The mechanical endurance is rated at 15 000 operations.

Frequently asked questions

Where can I buy 3VA1150-5EF32-0AG0 and how do I get a price?

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

What is the closest functional second-source to 3VA1150-5EF32-0AG0?

The closest peer in the same SENTRON 3VA family is 3VA1110-5EE32-0DC0, but it is a different frame size and rating. The 3VA1150-5EF32-0AG0 carries a 50 A continuous rating and 187 kA interrupting at 240 V, while the 3VA1110-5EE32-0DC0 is a lower-current variant. Panel cutout and bus spacing differ — verify dimensions before substituting.

What compliance documentation does this brand provide for 3VA1150-5EF32-0AG0?

Siemens SENTRON 3VA breakers are typically covered by UL, CSA, and IEC certifications. RoHS and REACH declarations are available through Siemens' documentation portal. Specific approval markings for this order code should be verified on the nameplate or via the manufacturer's declaration of conformity.
