The 3-pole frame delivers a 330 kA interrupting rating at 240 V, stepping down to 242 kA at 415/440 V and 187 kA at 500 V — enough headroom for most industrial main or feeder applications with high available fault current. With no undervoltage release and no ground-fault monitoring version fitted, it's a straight line-protection device; add external modules if those functions are needed. Rated insulation voltage: 800 V. Power loss max: 0.6 W. Storage temperature: -40 °C to 80 °C. Trip indicator: not fitted. Voltage trigger: not fitted. Communication function is built into the ETU850, enabling remote monitoring and parameterization via the SENTRON communication bus.","metaTitle":"Siemens 3VA2125-7KP32-0AA0 SENTRON MCCB, 25 A, 3-Pole, ETU85","metaDescription":"Siemens SENTRON 3VA2125-7KP32-0AA0 molded case circuit breaker, 25 A rated, 3-pole, ETU850 electronic trip unit, 330 kA at 240 V.
