Breaking capacity reaches 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.8 kA at 690 V — the 330 kA figure at 240 V covers high-fault utility feeds, while the 3.8 kA at 690 V still clears a substantial fault on 690 V industrial networks. ## ETU860 release and ground-fault monitoring The overcurrent release is an ETU860 electronic trip unit with adjustable response times: tr from 0.5 to 25 and tsd up to 0.5 s. Communication function is built in, supporting integration with higher-level monitoring systems. Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a standard 3-pole MCCB footprint for the SENTRON 3VA platform. Power loss is a maximum of 4 W, which keeps heat dissipation low in a crowded panel.","metaTitle":"Siemens 3VA2163-7KQ32-0AA0 SENTRON MCCB, 63 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA2163-7KQ32-0AA0 molded case circuit breaker, 63 A rated continuous current, 3-pole, line protection with ETU860 release.
