At the most common industrial distribution voltages (400–480 V), this breaker handles fault currents well above typical available fault levels in most panelboards — you are unlikely to need a current-limiting upstream device for coordination. ## Thermal performance and panel integration Above 55 °C it steps down: 60.6 A at 55 °C, 58.3 A at 60 °C, 55.9 A at 65 °C, and 53.6 A at 70 °C. If your panel runs hot (poor airflow, high density of breakers), factor the 55 °C curve into your load schedule. The 3VA2063-5HL32-0CA0 is a line-protection variant with an undervoltage release. The base switch without the UVR is order code 3VA2063-5HL32-0AA0; the integrated auxiliary trip used in this assembly is 3VA9608-0BB24. If you already have a panel designed around the base switch, the UVR-equipped version adds one additional control wire (the undervoltage coil) — no rewiring of the main power path needed.","metaTitle":"Siemens 3VA2063-5HL32-0CA0 SENTRON MCCB, 63 A, 3-pole","metaDescription":"Siemens 3VA2063-5HL32-0CA0 SENTRON molded case circuit breaker, 63 A rated, 3-pole, 187 kA at 240 V, undervoltage release included.
