The Siemens 3VA1063-2ED36-0AD0 is a SENTRON 3VA molded case circuit breaker rated for line protection, carrying a 63 A continuous current at 40 °C ambient with no derating needed up to 50 °C — it holds 63 A flat through 50 °C, then drops to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C, so in a warm enclosure you still have headroom before the thermal element nudges the trip curve. The TM210 overcurrent release is a thermal-magnetic design — the thermal bimetal handles overload protection (inverse-time), the magnetic coil handles short-circuit instantaneous trip. Breaking capacity climbs with available fault current: 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. Three-pole, 70 mm deep, 76.2 mm wide, 130 mm tall — standard 3VA frame footprint. The 17.3 W maximum power loss at rated current is the heat you need to vent in a sealed enclosure; at 63 A that is about 0.27 W per amp, which is typical for a thermal-magnetic MCCB of this frame size.
Spring-cage or screw terminals on the load side — the order code variant determines termination; this code ships with the standard screw terminals for the 3VA frame. The auxiliary switch block (3 auxiliary switches HQ) is a separate orderable accessory that clips onto the left side of the breaker — it is not integrated into this base unit. If you need a trip-indicated auxiliary contact, order the switch block separately and snap it on before panel wiring.
