It carries a continuous rated current of 25 A across the full ambient temperature range from 40 °C to 70 °C (–), meaning no derating curve to chase when the panel runs hot — that 25 A holds steady. The interrupting ratings are what decide the fit: 330 kA at 240 V, 242 kA at 415 V and at 440 V, 187 kA at 500 V, and 3 kA at 690 V. At 415 V, that 242 kA SCCR covers most industrial service-entrance and feeder applications without needing a current-limiting fuse upstream. The ETU350 electronic trip unit provides adjustable overload and short-circuit protection curves — it's the middle-tier release in the 3VA2 family, giving you LSI (long-time, short-time, instantaneous) protection with a wider coordination window than a thermal-magnetic breaker. ## Panel integration and mounting The 3VA2025-7HN36-0AA0 occupies 105 mm width, 181 mm height, and 86 mm depth — a 3-pole MCCB in the standard 3VA2 frame. It mounts via screw terminals onto a DIN rail or directly to a backplate; the IP40 front protection means it's suited for enclosed distribution boards where the front face is behind a door or cover, not for open-panel washdown areas. No communication module, no undervoltage release, no ground-fault monitoring — this is a straight line-protection breaker, not a multifunction device.","metaTitle":"Siemens 3VA2025-7HN36-0AA0 SENTRON MCCB, 25 A, 3-Pole, 330 k","metaDescription":"Siemens 3VA2025-7HN36-0AA0 SENTRON molded case circuit breaker, 25 A continuous, 3-pole, ETU350 release, 330 kA SCCR at 240 V.
