It carries a continuous 63 A at 40 °C through all temperature points up to 70 °C — no derating needed across that span, which simplifies panel sizing in warm enclosures. The 330 kA interrupting rating at 240 V gives serious fault-current headroom for industrial distribution where the available fault current is high — think main or feeder duty in a plant with large transformers. At 415 V it still holds 242 kA, so it handles most low-voltage industrial supplies without needing a current-limiting fuse upstream. Three auxiliary switches (HQ design) are built in for remote status feedback — useful for a PLC input or a panel lamp showing the breaker state without opening the door. The basic switch assembly underneath is order code 3VA2163-7MN32-0AA0, meaning the base switching cell is a separate line item if you ever need just that core. ## Physical fit and panel integration At 105 mm wide, 181 mm tall, and 86 mm deep, this 3-pole MCCB fits standard SENTRON mounting footprints. The 86 mm depth is shallow enough for most 200 mm deep enclosures with room behind for wiring — no need to force it into a deeper can just for the breaker. Maximum power loss is 4 W, so heat dissipation inside a sealed panel is minimal — no special ventilation slot needed for this single breaker.","metaTitle":"Siemens 3VA2163-7MN32-0AD0 SENTRON MCCB, 63 A, 3-Pole, 330 k","metaDescription":"Siemens 3VA2163-7MN32-0AD0 SENTRON molded case circuit breaker. 63 A rated at 40 °C, 3-pole, 330 kA at 240 V.
