Insulation voltage is rated at 800 V, giving you margin on 690 V systems where the interrupting capacity drops to 3.7 kA — that's the limit to watch if you're feeding a 690 V motor drive. ## Communication and integration This MCCB includes a communication function, meaning it can report status and trip events to a higher-level control system — useful for a cold-storage plant where you want remote indication of a breaker trip in a freezer without sending a technician to the panel. No ground-fault monitoring is built in; that would require a separate module or a different variant.","metaTitle":"Siemens 3VA2140-6JP46-0AA0 SENTRON MCCB, 40 A, 4-Pole, ETU55","metaDescription":"Siemens SENTRON 3VA2140-6JP46-0AA0 molded case circuit breaker, 40 A continuous, 4-pole, ETU550 electronic trip unit, 242 kA interrupting at 240 V.
