What the ratings mean for fit
The 3VA1063-4ED36-0AF0 is a 3-pole SENTRON molded case circuit breaker rated 63 A continuous at 40 °C — that's the full-rated current without derating up to 50 °C, where it still holds 63 A. Above that, it steps down: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. If your panel ambient runs above 50 °C, size the breaker for the derated figure, not the nameplate 63 A. The interrupting ratings tell you where this breaker can clear a fault without welding or rupturing: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. For a 480 V panel, that's well above typical available fault current, so it's a strong candidate for high-fault installations like transformer secondaries or large motor control centers. The TM210 overcurrent release is a fixed thermal-magnetic trip — no electronic adjustment, no communication module, no ground-fault monitoring. That keeps the part simple and reliable for standard feeder protection, but it's not the right choice if you need adjustable long-time or short-time pickup curves.
Panel fit and wiring
Mounts on a standard DIN rail or panel-mount base. Dimensions are 76.2 mm wide by 130 mm high by 70 mm deep — the width is a standard 3-pole MCCB footprint, so it drops into existing SENTRON or 3VA-series cutouts without panel rework. The front face carries an IP40 rating, meaning it's protected against tools and wires but not against water ingress; keep it inside a sealed enclosure if washdown is present. Comes with one auxiliary switch and one trip alarm switch (HQ version) factory-installed. That gives you a Form-C contact for status feedback and a separate contact that closes only on a trip event — useful for remote annunciation or PLC inputs without adding external relays.
