Line protection version, no ground fault monitoring, no communication module. The 242 kA at 240 V is the headline figure, but the real-world value for a 400 A frame is the 187 kA at 415 V — that's the common low-voltage distribution level across most industrial plants. At 690 V it still clears 40 kA, which keeps this breaker usable on 690 V delta systems common in mining and heavy process. The ETU320 trip unit supports adjustable long-time, short-time, and instantaneous settings, so you can coordinate downstream breakers for selective tripping rather than a full bus blackout. At 55 °C it derates to 385 A, at 60 °C to 370 A, at 65 °C to 355 A, and at 70 °C to 340 A. The 138 mm width, 248 mm height, and 110 mm depth fit standard Siemens 3VA switchboard mounting; no special adapter needed for most SENTRON distribution panels. This is a current-production part — no phase-out notice on record. The 3VA2 frame is Siemens' mainline MCCB platform, so spares and replacements are stable through normal distribution.","metaTitle":"Siemens 3VA2340-6HL32-0JL0 SENTRON MCCB, 400 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2340-6HL32-0JL0 molded case circuit breaker, 400 A rated continuous current, 242 kA interrupting at 240 V.
