It carries 63 A continuous at 40 °C through all ambient points up to 70 °C — no derating needed across that range, which simplifies panel sizing in warm enclosures. Three-pole construction, with interrupting ratings of 187 kA at 240 V AC and 121 kA at 415/440 V AC. At 690 V the rating drops to 3.7 kA — still adequate for most industrial line-side faults, but verify against your available fault current if feeding a 690 V bus.
Built-in accessories and panel fit
The auxiliary contacts report position back to a PLC or status lamp without extra wiring. Footprint is 105 mm wide × 181 mm tall × 86 mm deep — a standard SENTRON 3VA frame size that fits existing Siemens panel cutouts and busbar systems. No communication module on board; this is a standalone thermal-magnetic breaker, not a metering or networked unit.
