This MCCB carries a 63 A rating across ambient temperatures from 40 °C to 50 °C, with a gentle derating curve starting at 55 °C (60.6 A) down to 53.6 A at 70 °C — useful for panels with limited airflow or high internal heat rise. The basic switch variant (without trip unit) is order code 3VA2163-5JQ32-0AA0, which may be relevant for replacement of the switching mechanism alone. Communication function is built in, supporting integration into higher-level monitoring without an external module. ## Trip unit and protection features The ETU560 electronic trip unit offers adjustable protection curves for line protection. A trip indicator is present for quick fault identification during troubleshooting. No undervoltage release or phase failure detection is fitted on this variant; those functions would require a different order code or add-on module. Maximum power loss is 4 W, which is low enough to avoid significant heat buildup in a densely packed panel.","metaTitle":"Siemens 3VA2163-5JQ32-0AH0 SENTRON MCCB, 63 A, 187 kA","metaDescription":"Siemens SENTRON 3VA2163-5JQ32-0AH0 molded case circuit breaker, 63 A rated continuous current, 187 kA breaking capacity at 240 V.
