Product details

32 A transformer-protection breaker with CLASS 10 trip

Breaking capacity runs 100 kA at 240 V AC, 50 kA at 400 V AC, 10 kA at 500 V AC, and 4 kA at 690 V AC — so at common 400 V distribution this breaker handles high fault currents typical of transformer secondary circuits. Any mounting position allowed. The 55 mm width fits standard panel layouts; depth is 149 mm, height 140 mm. Finger-safe touch protection on the front (IP20) means it can sit in open-back enclosures without additional shrouding.

Main circuit terminals are screw-type with box terminals. Accepts 2x (0.75... 16 mm²) solid or 2x (0.75... 25 mm²) stranded, plus a single 0.75 … 35 mm² stranded. AWG equivalents: 2x (18... 2) solid, 1x (18... 2). Auxiliary and control circuits also use screw terminals. Fine-stranded with core-end processing: 2x (0.75... 16 mm²) or 0.75... 25 mm². Power dissipation at AC in hot operating state is 19 W total, 6.3 W per pole. Plan for that heat load in dense panel layouts — the 55 mm width leaves some air gap between adjacent breakers, but derating may apply above 40 °C ambient.

Shock resistance 25 g / 11 ms. Substance prohibitance date 07/01/2006 — this part complies with RoHS-style restrictions from that date. Surge voltage resistance rated 6 000 V.

Frequently asked questions

Where can I buy 3RV1431-4EA10-0BA0 and get a price?

This part 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 quote.

What is the breaking capacity of 3RV1431-4EA10-0BA0 at 400 V?

50 kA at 400 V AC, which is the typical secondary voltage for distribution transformers. At 240 V it is 100 kA, at 500 V it is 10 kA, and at 690 V it is 4 kA.

Does 3RV1431-4EA10-0BA0 have phase failure detection?

Yes, phase failure detection is included. Ground fault detection is not.

What compliance documentation does this part carry?

The part has a substance prohibitance date of 07/01/2006, indicating RoHS-style compliance. Surge voltage resistance is rated 6 000 V. Standard SIRIUS documentation includes CE, UL, and CSA certifications per the series.
