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.","metaTitle":"Siemens 3VA1163-3EF32-0AD0 SENTRON MCCB, 63A, 3-Pole, 75.6kA","metaDescription":"Siemens SENTRON 3VA1163-3EF32-0AD0 molded case circuit breaker, 63A rated at 40°C, 3-pole, TM240 release. 75.6kA interrupting at 240V.
