It carries a rated continuous current Iu of 63 A with an interrupting capacity of 187 kA at 240 V, 121 kA at 415 V, and 79 kA at 500 V. The 63 A rating holds flat from 40 °C through 50 °C (–); above that it derates gradually to 53.55 A at 70 °C, so if your panel ambient runs hot, size accordingly.
Trip unit, auxiliaries, and communication
The overcurrent release is an ETU550 — an electronic trip unit with adjustable long-time, short-time, instantaneous, and ground-fault protection curves. It gives you selectivity coordination options that a thermal-magnetic can't match. Communication function is built in, so it can talk to a higher-level energy management or monitoring system without an add-on module. No undervoltage release is fitted, and there is no phase-failure detection — that's handled by the ETU if needed.
The 3VA2163-5JP32-0JC0 is a 3-pole MCCB with dimensions of 105 mm width, 181 mm height, and 86 mm depth (–). That 86 mm depth is the projection behind the panel face — important when you're fitting it into a shallow enclosure or a retrofit where the backpanel clearance is tight.
