The interrupting capacity tells the real story: 330 kA at 240 V, 242 kA at 415 V, and 3.75 kA at 690 V. ## Trip unit and protection features The ETU860 electronic release handles the overcurrent protection curve. A shunt trip (STL) is integrated for remote tripping. The breaker also includes a voltage trigger and a trip indicator — useful for fault isolation during commissioning. No undervoltage release or phase failure detection on this variant, so if those are required, this isn't the pick.","metaTitle":"Siemens 3VA2125-7KQ32-0JL0 SENTRON MCCB, 25 A, 3-pole","metaDescription":"Siemens SENTRON 3VA2125-7KQ32-0JL0 molded case circuit breaker, 25 A rated, 3-pole, ETU860 release, 330 kA at 240 V.
