The breaker is rated for a maximum ambient of 75 °C and a minimum of -40 °C, with humidity limits: 95% RH up to 55 °C, 55% RH to 70 °C, 35% RH to 75 °C. This matters when the panel is in a hot enclosure or near process heat — verify the actual ambient at the mounting location to avoid nuisance tripping at full load. Installation depth is 70 mm. The fastening method is a quick-assembly system — clips onto the rail without tools. Degree of pollution 3 (conductive pollution, typical for industrial control panels). Touch protection is provided.","metaTitle":"Siemens 5SY7363-8CC SENTRON MCB, 3P D 63 A, 15 kA","metaDescription":"Siemens 5SY7363-8CC SENTRON miniature circuit breaker, 3-pole, D-curve, 63 A, 15 kA breaking capacity per IEC 60947-2.
