The minimum setting of 95 A means you cannot set it below that, even if the connected load is smaller; the frame size is the floor. This version includes a communication function and an 'other measurement function' — the ETU850 can report load current and trip events over the communication bus, which is useful for energy monitoring or remote troubleshooting without climbing to the panel. No ground-fault monitoring is built in, and there is no undervoltage release or trip indicator on this variant. Max power loss is 4 W, which is low for a 63 A frame with an electronic trip unit — keeps heat out of the enclosure and simplifies thermal calculations in a packed panel. Operating range of -25 °C to 70 °C suits most indoor industrial environments without special heating or cooling.","metaTitle":"Siemens 3VA2163-7KP42-0AA0 SENTRON MCCB, 63 A, 4-Pole, ETU85","metaDescription":"Siemens SENTRON 3VA2163-7KP42-0AA0 molded case circuit breaker, 63 A rated, 4-pole, ETU850 electronic trip unit, 330 kA at 240 V.

The 3VA2163-7KP42-0AA0 uses the ETU850 electronic trip with communication; the 8HM32 variant has a different trip curve and accessory set. They share the same mounting footprint and busbar connections, so a panel designed for one can accept the other without rewiring — but the protection settings and communication capability differ, so verify the trip unit matches the protection study before swapping."},{"question":"Does this MCCB include ground-fault monitoring or an undervoltage release?","answer":"No. This variant is specified without ground-fault monitoring and without an undervoltage release. It also does not include a trip indicator.
