Rated 50 A continuous at 40 °C, it holds that full rating through 50 °C before derating begins — at 55 °C it's 49 A, at 70 °C it's 45 A — so in a warm enclosure you still get nearly full ampacity. Breaking capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — these numbers tell you it can interrupt very high fault currents at the common low-voltage distribution levels, which matters when the available fault current at the panel is above 25 kA.
Three-pole, 70 mm deep, 76.2 mm wide, 130 mm tall — fits standard DIN-rail or direct-mount MCCB footprints used across SENTRON 3VA family panels. Rated insulation voltage 800 V, so it's suitable for 480/277 V and 600/347 V distribution systems common in North American and IEC panels.
Overcurrent release and auxiliary contacts
Trip indicator (mechanical flag) visible on the front — lets a technician walking the panel see which breaker tripped without opening the door.
Still a standard catalog item from Siemens.
