The 187 kA breaking capacity at 240 V is the headline number, but the real-world fit depends on the voltage on your bus: at 415 V and 440 V it still interrupts 121 kA, dropping to 79 kA at 500 V and 4.25 kA at 690 V. The ETU850 is a programmable electronic trip with communication capability, so it integrates into a monitored distribution system rather than being a passive thermal-magnetic device. At 55 °C it drops to 60.6 A, at 60 °C to 58.3 A, and at 70 °C to 53.6 A. If your enclosure runs hot (stacked drives, poor airflow), size the upstream conductor and downstream load for the derated value at your actual ambient. The breaker measures 105 mm wide × 181 mm high × 86 mm deep — standard 3-pole MCCB footprint for a 160 A frame, so it fits existing SENTRON mounting bases and busbar systems without panel rework. ## Auxiliaries and releases Maximum power loss is 6.5 W, negligible for panel thermal budgeting.","metaTitle":"Siemens 3VA2163-5KP32-0DH0 SENTRON MCCB, 63 A, 3-Pole, ETU85","metaDescription":"Siemens SENTRON 3VA2163-5KP32-0DH0 molded case circuit breaker, 63 A rated, 3-pole, ETU850 trip unit.
