The electronic trip unit is an ETU560, which gives you adjustable long-time, short-time, and instantaneous protection curves. That matters when you're coordinating with downstream breakers — you can shape the trip to avoid nuisance trips on motor inrush. The breaker also has a communication function, so it can talk to a BMS or PLC for remote monitoring and trip event logging. That UVR is handy for safety circuits — if the control voltage drops, the breaker opens without waiting for an overcurrent event. ## Temperature derating — don't ignore it Above that, it starts to step down: 60.6 A at 55 °C, 58.3 A at 60 °C, 55.9 A at 65 °C, and 53.6 A at 70 °C.","metaTitle":"Siemens 3VA2163-5JQ42-0GF0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2163-5JQ42-0GF0 molded case circuit breaker, 63 A rated, 187 kA interrupting at 240 V.
