At 690 V the 3 kA figure is a derate; if your system runs that voltage with fault currents above 3 kA, step up to a higher-rated frame. No derating curve to calculate — the ETU860 handles it electronically. Ambient at 70 °C is common inside sealed cement-plant or steel-mill enclosures; this breaker eats the dust and runs without a current haircut. ## Trip unit and protection features The ETU860 electronic overcurrent release gives you adjustable N-conductor protection (OFF, 40% to 160% of Iu) and ground-fault monitoring via summation current formation on the L-conductor. Communication function is onboard, so it talks to a higher-level system for metering and trip events. No undervoltage release, no voltage trigger, no trip indicator on this variant — those are separate accessory add-ons.","metaTitle":"Siemens 3VA2025-6KQ32-0AA0 SENTRON MCCB, 25 A, 242 kA at 240","metaDescription":"Siemens 3VA2025-6KQ32-0AA0 SENTRON molded case circuit breaker, 25 A rated, 242 kA interrupting at 240 V, 3-pole, ETU860, IP40 front.
