No ground-fault monitoring or N-conductor protection built in; those are external add-ons if the application requires them. Breaking capacity varies by line voltage: 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Rated insulation voltage Ui = 800 V, max operational voltage with DC = 600 V. Dimensions: 130 mm height, 101.6 mm width, 70 mm depth. Motor drive option is available as a product extension (Product Extension / Optional / Motor Drive = Yes), meaning the breaker accepts a remote motor operator for electrical trip-and-close control — useful for remote or automated panel applications.","metaTitle":"Siemens 3VA1112-3EE42-0AA0 SENTRON MCCB, 125A 4-Pole, 75.6kA","metaDescription":"Siemens 3VA1112-3EE42-0AA0 SENTRON molded case circuit breaker, 125A continuous, 4-pole, TM220 release.
