The Siemens SENTRON 3VA1163-3EF32-0AD0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection. It carries 63 A continuously at 40 °C with no derating through 50 °C, then steps down to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C — useful to know when the breaker lives next to other heat sources in a crowded panel. The TM240 thermal-magnetic release provides fixed overload and short-circuit protection, with no voltage-trip or undervoltage-release option on this variant. Interrupting capacity hits 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V — that SCCR curve covers most industrial distribution voltages in a single frame.
Panel Fit & Integration
Dimensions are 76.2 mm wide (3 in), 130 mm tall (5.12 in), and 70 mm deep (2.76 in) — a standard 3-pole MCCB footprint that drops into most DIN-rail or panel-mount bases without re-drilling. The design accepts up to 3 auxiliary switches (HQ type) for remote status feedback. Insulation voltage rated at 800 V, with a maximum power loss of 17.3 W at full load. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. No ground-fault monitoring or communication function on this variant — it's a straight thermal-magnetic line-protection device.
