That's unusual; most breakers start tapering above 40 °C. It means the 63 A marking is the real-world ampacity, not a catalog number you have to knock down. It bolts into a panel base or mounts on a mounting plate; no DIN-rail clip on this frame size. The 3VA2063-5HN32-0AG0 ships with a factory-installed auxiliary switch and trip alarm switch (1 each, HP type). The base switch assembly is order code 3VA20635HN320AA0 — useful to know if you're stocking spare internal mechanisms rather than whole breakers.","metaTitle":"Siemens 3VA2063-5HN32-0AG0 SENTRON MCCB, 63 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2063-5HN32-0AG0 molded case circuit breaker, 63 A rated, 3-pole, 187 kA at 240 V.
