The 3-pole frame with IP40 front protection is sized for main feeder or large branch protection in a 600 V class panel. At 240 V the MCCB clears 187 kA — that's a very high interrupting rating, suited for transformer secondary or high-fault industrial mains. The rating drops to 121 kA at 415 V and 440 V, then to 79 kA at 500 V, and 4.25 kA at 690 V. The thermal curve holds 63 A continuously up to 50 °C ambient; above that it derates linearly to 53.55 A at 70 °C. That means the breaker can sit in a warm enclosure without needing to oversize the frame, as long as the load stays under the derated value. ## Trip unit and auxiliary contacts The ETU350 is a microprocessor-based electronic trip unit with LSI protection curves — long-time, short-time, and instantaneous adjustable. It gives finer coordination than a thermal-magnetic trip, especially for downstream selective tripping. No undervoltage release or shunt trip is installed on this variant. That's a standard 3VA3 frame footprint — it drops into the same mounting cutout and bus-bar spacing as other 3VA3 breakers. If you're replacing a 3VA2163-5HN36-0AA0 (the basic switch without the trip alarm), this -0AG0 variant adds the alarm contact without changing the physical envelope. Panel wiring and gland-plate layout stay the same.","metaTitle":"Siemens 3VA2163-5HN36-0AG0 MCCB, 63 A, 187 kA at 240 V","metaDescription":"Siemens SENTRON 3VA2163-5HN36-0AG0 molded case circuit breaker, 63 A rated, 187 kA breaking at 240 V.
