Interrupting capacity is substantial: 242 kA at 240 V, 187 kA at 415 V, and still 121 kA at 500 V. The 3VA2040-6HN36-0AA0 is a 3-pole breaker that mounts on DIN rail or direct panel. Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — that's a 4.13 x 7.13 x 3.39 inch footprint. The IP40 front rating means it's suitable for installation in a standard electrical enclosure with a door.","metaTitle":"Siemens 3VA2040-6HN36-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU35","metaDescription":"Siemens SENTRON 3VA2040-6HN36-0AA0 molded case circuit breaker, 40 A continuous, 3-pole, ETU350 electronic trip unit.
