Its interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V, so it handles high-fault scenarios typical in industrial distribution without cascading upstream. It's equipped with the ETU560 electronic trip unit, which gives adjustable N-conductor protection (OFF, 40 % to 160 % of Iu) and ground-fault monitoring via summation current formation on L + N. The unit communicates — the communication function is built in — so it can talk to a higher-level control system for status and metering without an add-on module. The 86 mm depth, 140 mm width, and 181 mm height fit the standard SENTRON panel footprint. No LTB clock is ticking. The ETU560 release and communication function mean it's ready for modern switchgear that needs remote monitoring or selective coordination studies. If your cabinet ambient stays under 70 °C, you get the full 25 A per pole. The interrupting capacity at 415 V (187 kA) is typical for a high-fault industrial service entrance or a large sub-distribution board. The IP40 front is standard for a panel-mounted device; the enclosure provides the rest of the ingress protection. The unit is designed to meet IEC 60947-2 for MCCBs. For specific compliance documents (RoHS, REACH, UL file number), the manufacturer provides declarations on request — the part carries the CE mark and is listed for the European market.","metaTitle":"Siemens 3VA2025-6JQ42-0AA0 SENTRON MCCB, 4P, 25A, 242kA at 2","metaDescription":"Siemens SENTRON 3VA2025-6JQ42-0AA0 molded case circuit breaker, 4-pole, 25 A, 242 kA at 240 V.
