Breaking capacity climbs to 242 kA at 240 V and stays at 187 kA through 415–440 V, then drops to 121 kA at 500 V and 3.7 kA at 690 V. The 3VA2140-6KP32-0AA0 measures 105 mm wide, 181 mm tall, and 86 mm deep — a 3-pole frame that occupies a standard MCCB cutout in a distribution board. No undervoltage release is fitted, and there is no voltage-trip accessory on board. A communication function is present, and the breaker includes an other measurement function, meaning it can report current and power data over the SENTRON communication bus — useful for energy monitoring without an external transducer. The trip indicator is absent, so there is no local mechanical flag showing the breaker has tripped on fault — rely on the communication output or a separate auxiliary contact.","metaTitle":"Siemens 3VA2140-6KP32-0AA0 SENTRON MCCB, 40 A, 60–480 A trip","metaDescription":"Siemens 3VA2140-6KP32-0AA0 SENTRON molded case circuit breaker, 40 A continuous, adjustable trip 60–480 A, ETU850 electronic trip unit. 242 kA at 240 V.
