That 630 A holds flat through 50 °C — only starts to derate above 55 °C, dropping to 583 A at 70 °C. So for most panel environments below 50 °C, you get full rated current without a derate factor to calculate. Breaking capacity runs 121 kA at 240 V AC, 76 kA at 415 V and 440 V, and 53 kA at 500 V AC. It carries a TM220 overcurrent release — thermal-magnetic, fixed, no electronic adjustment. The 220 designation is Siemens' internal code for the trip curve family. No undervoltage release, no shunt trip, no communication module — this is a straight thermal-magnetic breaker for basic distribution.
Mounts in a standard switchboard or panel enclosure. Dimensions: 248 mm tall, 184 mm wide, 110 mm deep. That 184 mm width is the panel cutout dimension to plan for; it's a 4-pole frame, so wider than a 3-pole equivalent. Maximum power loss is 193 W at full rated current.
