{"schemaVersion":"matrix-product-facts/v1","identity":{"mpn":"3VA1216-4GF42-0AA0","brand":"Siemens","brandSlug":"siemens","productSlug":"3VA1216-4GF42-0AA0","canonicalUrl":"https://aoctrl.com/siemens/3VA1216-4GF42-0AA0","factsUrl":"https://aoctrl.com/api/mcp/products/3VA1216-4GF42-0AA0","rawCanonicalId":null},"summary":{"shortDescription":"Siemens SENTRON 3VA molded case circuit breaker, 3VA1216-4GF42-0AA0, 160 A, 4-pole, TM240 thermal-magnetic overcurrent release, line protection version, breaking capacity 121 kA at 240 V AC.","salesMarkdown":"The 121 kA breaking capacity at 240 V AC (75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, 11.9 kA at 690 V) gives it the interrupting capability for high-fault industrial services where the available short-circuit current is substantial. The 160 A rating holds flat from 40 °C through 50 °C, then derates linearly to 142 A at 70 °C — a useful thermal curve for panels that run warm. The N-conductor is protected at 100% rating, meaning the neutral pole carries the same continuous current as the phase poles. Physically it measures 158 mm tall, 140 mm wide, and 70 mm deep — a 4-pole frame that fits standard SENTRON 3VA panel cutouts. ## Breaking capacity by voltage — selectivity headroom The interrupting ratings span the common industrial voltages: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V. These are the ultimate short-circuit breaking capacities (Icu) per IEC 60947-2. For a site electrical engineer checking selectivity coordination, the 75.6 kA at 415 V is the figure that governs most European 400 V distribution panels — it gives headroom above typical transformer-fed fault levels (often 25–50 kA at the main switchboard). The 690 V rating of 11.9 kA is lower but still adequate for most 690 V motor control centers. ## Optional motor drive and communication The product extension field notes that a motor drive is available as an option — meaning this breaker frame accepts a remote-operated motor mechanism for electrical closing and opening, useful in SCADA or remote-controlled distribution. The communication function is listed as No, so this base variant does not include a communication module; if bus connectivity (PROFIBUS, PROFINET, Modbus) is required, a different 3VA variant with the communication option would be needed. ## Power loss and environmental limits Maximum power dissipation is 33 W at rated current — relevant for thermal calculations inside a sealed enclosure.","metaTitle":"Siemens 3VA1216-4GF42-0AA0 SENTRON MCCB, 160A, 4-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1216-4GF42-0AA0 molded case circuit breaker, 160A, 4-pole, TM240 release.
