{"schemaVersion":"matrix-product-facts/v1","identity":{"mpn":"3VA1080-4ED32-0BH0","brand":"Siemens","brandSlug":"siemens","productSlug":"3VA1080-4ED32-0BH0","canonicalUrl":"https://aoctrl.com/siemens/3VA1080-4ED32-0BH0","factsUrl":"https://aoctrl.com/api/mcp/products/3VA1080-4ED32-0BH0","rawCanonicalId":null},"summary":{"shortDescription":"Siemens SENTRON 3VA1080-4ED32-0BH0, molded case circuit breaker, 3-pole, 80 A rated continuous current Iu, TM210 thermal-magnetic release, line protection version, 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 11.9 kA at 690 V.","salesMarkdown":"## 80 A MCCB with TM210 Release — Line Protection for Distribution Panels The 80 A rating holds flat from 40 °C through 50 °C, then derates to 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C — meaning the breaker delivers full rated current in most ventilated enclosures but needs a 5–10 % headroom margin if the panel ambient runs above 50 °C. Breaking capacity reaches 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V — figures that place it in the high-interrupting category for 400 V-class distribution, suitable for transformer-fed main feeders or large motor control centers where fault currents exceed 50 kA. ## Fit and Integration — Panel Dimensions and Auxiliary Wiring The 3VA1080-4ED32-0BH0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that bolts into SENTRON distribution blocks or panel-mount chassis without special adapters. The undervoltage release (UVR) is factory-fitted as standard — design code confirms the UVR is built in, not a field-add option. For installations needing a separate shunt trip or auxiliary release, the factory accessory order code is 3VA9608-0BB11. ## TM210 Release and Protection Characteristics No electronic adjustment, no communication module, no phase-failure detection. This is a straightforward line-protection breaker for fixed-setting distribution; if you need adjustable long-time or short-time delays, step up to the electronic release variants in the 3VA series. Mechanical endurance is 15,000 operations — typical for a distribution MCCB not cycled daily.","metaTitle":"Siemens 3VA1080-4ED32-0BH0 SENTRON MCCB, 80 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1080-4ED32-0BH0 molded case circuit breaker, 80 A rated continuous current, 3-pole, TM210 release, 121 kA at 240 V.
