That thermal curve means you can load it to nameplate in a 55 °C panel without oversizing. Interrupting capacity runs 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Three-pole, no undervoltage release, no trip indicator, no communication function. The TM220 overcurrent release is the standard thermal-magnetic type — thermal for overload, magnetic for short-circuit. Dimensions: 130 mm height, 76.2 mm width (3 in), 70 mm depth (2.76 in). Width at 76.2 mm matches standard 3-pole MCCB footprints on DIN-rail or panel-mount adapters; verify the mounting base if replacing a different manufacturer's breaker. Maximum power loss is 17.3 W. The storage floor matters for unheated warehouses — this breaker can sit through a hard freeze without damage.","metaTitle":"Siemens 3VA1163-4EE32-0AA0 SENTRON MCCB, 63A 3P 121kA","metaDescription":"Siemens 3VA1163-4EE32-0AA0 SENTRON molded case circuit breaker, 63A at 40°C, 3-pole, 121kA at 240V.
