That's a solid thermal curve for a panel that runs warm. The interrupting ratings are the headline here: 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 3.4 kA at 690 V. The overcurrent release is an ETU350 electronic trip unit — that's the adjustable kind, so you can set the long-time pickup and short-time delay to coordinate with downstream breakers. No communication function, no phase failure detection, no ground fault monitoring on this variant. It's a straightforward line-protection breaker with an undervoltage release (UVR) built in. No auxiliary contacts come with this order code, so if you need a status feedback signal, you'll add the auxiliary trip block (order code 3VA9608-0BB11) separately. The basic switch assembly is listed as 3VA2063-5HN36-0AA0, which is the internal switching mechanism. Power loss is 7.9 W maximum at rated current — modest for a 63 A frame, so ventilation requirements in the enclosure are minimal.","metaTitle":"Siemens 3VA2063-5HN36-0BA0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2063-5HN36-0BA0 molded case circuit breaker, 63 A rated, 187 kA interrupting at 240 V.
