The 3-pole design includes phase failure detection, a communication function, and an additional measurement function, making it suitable for integration into monitored motor control centers. ## Motor Protection and Adjustable Trip Settings This MCCB is configured for motor protection duty, with an adjustable thermal-magnetic trip that can be set from a minimum of 3 s to a maximum of 30 s at the overload threshold, and an initial value of 5 A. The full-scale value is 25 A, matching the continuous current rating, and the breaker does not include an undervoltage release or voltage trigger, so it relies on the trip unit alone for fault clearing. ## Panel Integration and Environmental Limits The 3VA2125-7MQ32-0AA0 occupies a 105 mm width on the DIN rail, with a depth of 86 mm and height of 181 mm — a compact footprint for a 3-pole MCCB with this interrupting capacity. It operates from -25 °C to 70 °C ambient and can be stored from -40 °C to 80 °C, with maximum power dissipation of 0.6 W. The trip indicator is not present, so visual status confirmation requires a separate auxiliary contact or communication module.","metaTitle":"Siemens 3VA2125-7MQ32-0AA0 SENTRON MCCB, 25 A, 3-Pole, Motor","metaDescription":"Siemens 3VA2125-7MQ32-0AA0 SENTRON molded case circuit breaker, 25 A continuous, 3-pole, motor protection design, 330 kA SCCR at 240 V.
