Siemens SENTRON 3VA2063-7HN32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection. It carries 63 A continuous at 40 °C through 70 °C with no derating — that flat thermal curve simplifies panel sizing when ambient runs warm. The interrupting rating hits 330 kA at 240 V, 242 kA at 415 V, and 187 kA at 500 V, with a sharp drop to 3 kA at 690 V. That 330 kA figure at 240 V places it in the high-fault tier for industrial main or feeder duty where available short-circuit current is extreme.
Ratings and release
The overcurrent release is an ETU350 — an electronic trip unit with adjustable functions typical for selective coordination in industrial distribution. Rated insulation voltage is 800 V, covering 480/600 V systems with margin. The front face carries IP40 protection; the breaker itself is intended for enclosed panel mounting, not open washdown areas. No undervoltage release, no ground-fault monitoring, no communication module on this variant — it is a straight line-protection MCCB with optional motor drive (available as an add-on). Power loss is a modest 3 W maximum.
Integration dimensions
Dimensions are 105 mm wide, 181 mm high, 86 mm deep. The width is the critical fit dimension for multi-breaker panelboards — 105 mm is a standard 4-module footprint on most DIN-rail or busbar systems. Depth of 86 mm leaves clearance for rear-connected bus stabs or cable lugs in a typical 200 mm deep enclosure.
