Rated 63 A continuous at 40 °C, it holds that rating steady through 50 °C before it starts a gentle derate: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, 58 A at 70 °C (–). Breaking capacity is where this thing earns its keep: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V.
What's built in — auxiliary switches and shunt trip
The shunt trip lets a remote signal — from an E-stop, a safety relay, or a PLC — force the breaker open. The trip alarm switch changes state only when the breaker trips on fault, not on manual open, so a control system can tell the difference between a planned shutdown and a fault event. No undervoltage release on this unit, so if you need UVR for machine safety, this isn't the variant.
Lifecycle status is current — Siemens still builds this variant, so it's not a scavenger-hunt part. No EOL notice, no last-time-buy clock. That means you can spec it into a new panel design without worrying about a forced redesign next year. For volume or project pricing, send the RFQ with the order code and target quantity; availability and current pricing get confirmed at quote time through independent distribution channels.
Three-pole frame with a 76.2 mm width, 130 mm height, and 70 mm depth. The width, 76.2 mm (3 inches), is standard for a 3-pole MCCB in this class; it'll drop into the same footprint as other SENTRON 3VA frames.
