The Siemens SENTRON 3VM1163-3ED12-0AA0 is a 1-pole molded case circuit breaker (MCCB) with a TM210 thermal-magnetic release, rated 63 A at 40 °C and carrying a 53 kA interrupting capacity at 240 V AC — that's the figure that governs fault clearance on a 240 V line, not the 8 kA at 415 V. The TM210 release means the thermal element is fixed at 63 A (the '210' indicates the frame rating), so it's sized for a 63 A branch circuit and not adjustable. At 415 V AC the interrupting rating drops to 8 kA, which is typical for a 1-pole device on a line-to-neutral fault path.
Sizing and derating
The 63 A rating holds from 40 °C up to 50 °C, then derates linearly to 58 A at 70 °C. That means in a warm panel — say 55 °C — you're still good for 62 A continuous. The 1-pole width is 25.4 mm (1 inch), so it occupies one module on a DIN rail; depth is 70 mm, which fits standard distribution boards without a deep enclosure.
Panel integration
Snap-on DIN-rail mount, 25.4 mm wide per pole. The front face carries an IP40 rating — protected against tools and wires >1 mm, but not against water ingress, so keep it inside a panel or enclosure. No undervoltage release, no communication function, no ground-fault monitoring; it's a straight line-protection MCCB with a trip indicator absent.
