Dimensions are 105 mm wide (4.13 in), 181 mm tall (7.13 in), 86 mm deep (3.39 in) — that 86 mm depth includes the handle and terminals, so check gland-plate clearance on shallow enclosures. IP40 on the front face; the body is open to the panel interior for heat dissipation.","metaTitle":"Siemens 3VA2140-6HN36-0AA0 SENTRON MCCB, 40 A, 242 kA","metaDescription":"Siemens 3VA2140-6HN36-0AA0 SENTRON MCCB, 40 A continuous, 242 kA at 240 V, 3-pole, line protection, ETU350 release.
