Interrupting capacity is 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V. For a main breaker on a 480 V panel, the 187 kA figure gives substantial SCCR headroom above typical available fault currents — no coordination gymnastics needed to protect downstream gear. The trip unit is an ETU560 electronic release, which provides adjustable long-time, short-time, instantaneous, and ground-fault protection curves. The ground-fault monitoring uses summation current formation on the L-conductor. This is not a basic thermal-magnetic breaker — it requires proper programming at commissioning, and the settings should be locked after coordination study. ## Auxiliary and control wiring — what comes integrated That's enough feedback for a PLC to know the breaker position and whether it tripped on fault versus manual open — no separate aux kit needed. The shunt trip is factory-integrated, so verify the control voltage matches your trip circuit before wiring. Communication function is present on this unit, which means it can report status and trip events over a bus system — useful for a centralized power monitoring setup without pulling additional control wires back to the panel. ## Physical fit and mounting Maximum power loss is 162 W at rated current. That heat has to leave the enclosure — factor it into your thermal budget, especially if this breaker shares a compartment with other high-current devices. ## Environmental limits and storage","metaTitle":"Siemens 3VA2463-6JQ32-0JL0 SENTRON MCCB, 630 A, 242 kA","metaDescription":"Siemens SENTRON 3VA2463-6JQ32-0JL0 molded case circuit breaker. 630 A rated at 40 °C, 242 kA interrupting at 240 V. 3-pole line protection with ETU560 trip unit.
