Breaking capacity runs 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 7.5 kA at 690 V — covering most LV fault-current scenarios downstream of a transformer. At 110 mm deep × 138 mm wide × 248 mm tall, this breaker fits standard SENTRON 3VA mounting bases and busbar systems. The 138 mm width is a 3-pole frame — verify gland-plate cutout if retrofitting into a panel originally laid out for a different MCCB family. Depth is shallow enough for 200 mm-deep enclosures; no rear-access clearance needed beyond the standard 50 mm arc-chute vent gap.","metaTitle":"Siemens 3VA2340-7HL32-0CA0 SENTRON MCCB, 400 A, 3-pole, UVR","metaDescription":"Siemens SENTRON 3VA2340-7HL32-0CA0 molded case circuit breaker, 400 A continuous, 3-pole, 110 mm depth.
