63 A, 4-pole MCCB with TM210 release — line protection workhorse
The Siemens SENTRON 3VA1063-4ED42-0AA0 is a 4-pole molded case circuit breaker rated 63 A at 40 °C, built for line protection in distribution panels. It carries a TM210 thermal-magnetic overcurrent release — that means fixed thermal and magnetic trip settings, no adjustment dials, so what you spec is what you get on the shelf. Breaking capacity hits 121 kA at 240 V and still holds 75.6 kA at 415 V, which covers most commercial and light industrial service-entrance and feeder applications without needing a current-limiting upstream device.
Panel fit and integration
Front face carries IP40 protection — fine for enclosed distribution boards, not for washdown environments. Dimensions are 130 mm height, 101.6 mm width, 70 mm depth. Four-pole form factor means it occupies the same footprint as a 3-pole plus neutral pole in a single molded case; no separate neutral block to mount. No undervoltage release, no shunt trip, no communication module — this is the bare-bones line-protection variant. If you need auxiliary contacts or remote tripping, you're looking at a different order code in the 3VA family.
