That flat thermal curve simplifies panel sizing: the same 25 A frame handles a warm cabinet without a bump in conductor or enclosure rating. Breaking capacity runs 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.8 kA at 690 V. The ETU330 electronic trip unit provides adjustable long-time pickup (Ir) from 0.5 A to 25 A and adjustable long-time delay (tr) from 0.5 s to 17 s, letting you shape the trip curve to the load — motor start, feeder, or capacitor bank — without swapping the breaker. Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard MCCB footprint that fits a 3-pole SENTRON 3VA mounting base. Optional motor drive available as a product extension for remote trip or reclose — useful in unmanned substations or PLC-controlled distribution.","metaTitle":"Siemens 3VA2125-7HM32-0BK0 SENTRON MCCB, 25 A, 3-Pole, 330 k","metaDescription":"Siemens SENTRON 3VA2125-7HM32-0BK0 molded case circuit breaker, 25 A rated continuous current, 3-pole, ETU330 release, breaking capacity 330 kA at 240 V.
