The D tripping curve handles inrush from motor and transformer loads without nuisance trips. At 40 °C derate to 59.22 A, at 45 °C to 57.33 A, at 50 °C to 54.81 A, and at 55 °C to 51.03 A. Operating ambient range is -25 to +45 °C; storage range -40 to +75 °C. The 1.5 W maximum power dissipation matters for enclosure thermal budgeting when multiple units are ganged. ## Installation and wiring Two-pole 1P+N unit, 36 mm wide (2 width units), 90 mm tall, 77 mm deep with 70 mm installation depth. Touch protection is built in. Halogen-free and silicon-free construction. Listed as current production. This is an active SENTRON catalog line — no phase-out or last-time-buy notice on record.","metaTitle":"Siemens 5SU9354-8KK63 SENTRON RCBO, 63 A, Type A, 10 kA","metaDescription":"Siemens 5SU9354-8KK63 SENTRON RCD-operated circuit breaker, 63 A rated, Type A, 10 kA breaking capacity per EN 60898.
