The Siemens 3VA2063-6HM46-0AA0 is a SENTRON molded case circuit breaker, 4-pole, rated 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to the 70 °C operating maximum. Breaking capacity hits 242 kA at 240 V, 187 kA at 415 V and 440 V, and 121 kA at 500 V; at 690 V it drops to 3 kA. The ETU330 electronic trip unit handles line protection with adjustable N-conductor protection (OFF or 100%) and ground fault detection via summation current on L+N. Depth is 86 mm, width 140 mm, height 181 mm — fits standard panel cutouts for a 4-pole MCCB in this class.
Panel integration
Mounts on a DIN rail or direct panel mount. The 86 mm depth leaves clearance for standard gland plates and busbar stacks; 140 mm width fits a 4-pole MCCB slot. IP40 on the front keeps out tools and fingers — suitable for enclosed panels. No communication module onboard; this is a standalone line-protection breaker.
