{"schemaVersion":"matrix-product-facts/v1","identity":{"mpn":"3VA2340-7HN32-0JH0","brand":"Siemens","brandSlug":"siemens","productSlug":"3VA2340-7HN32-0JH0","canonicalUrl":"https://aoctrl.com/siemens/3VA2340-7HN32-0JH0","factsUrl":"https://aoctrl.com/api/mcp/products/3VA2340-7HN32-0JH0","rawCanonicalId":null},"summary":{"shortDescription":"Siemens SENTRON 3VA2340-7HN32-0JH0, molded case circuit breaker, 3-pole, 400 A rated continuous current, 330 kA breaking capacity at 240 V, line protection version with ETU350 trip unit and shunt trip.","salesMarkdown":"The Siemens SENTRON 3VA2340-7HN32-0JH0 is a 3-pole molded case circuit breaker rated for 400 A continuous current (Iu) with a 330 kA interrupting capacity at 240 V — that figure drops to 242 kA at 415 V and 52.5 kA at 690 V, so the SCCR headroom depends on your system voltage. The line-protection version means it's configured for feeder and main breaker duty, not motor protection. The operating temperature range is -25 °C to 70 °C, with derating starting at 55 °C (385 A at 55 °C, down to 340 A at 70 °C). Storage range is wider: -40 °C to 80 °C. ## Integration — panel fit and auxiliary wiring The breaker occupies 138 mm width, 248 mm height, and 110 mm depth — a standard SENTRON 3VA frame size for the 400 A class. It mounts directly to a mounting plate or DIN rail via the base; the 3-pole construction leaves the neutral pole external if needed. The auxiliary contact block (2+1 HQ) and the shunt trip (STL) are factory-integrated, so no field-assembly of those accessories is required — the order code 3VA2340-7HN32-0JH0 already includes them. The 330 kA breaking capacity at 240 V is the headline number, but the real-world selectivity study uses the 242 kA at 415 V or the 52.5 kA at 690 V — that's the value for a 400 V or 690 V distribution board. For a main breaker in a high-fault industrial panel, the 400 A continuous rating with 242 kA SCCR at 415 V covers most common LV switchgear applications. The 15,000 mechanical endurance cycles are typical for a fixed-mounted MCCB in a main or feeder role — not a switching-duty device, but adequate for infrequent operation.","metaTitle":"Siemens 3VA2340-7HN32-0JH0 SENTRON MCCB, 400A, 3-Pole, 330kA","metaDescription":"Siemens SENTRON 3VA2340-7HN32-0JH0 molded case circuit breaker, 400A rated continuous current, 3-pole, 330kA breaking at 240V.
