The electronic trip unit is adjustable — minimum setting 945 A, maximum 5670 A — which gives you selectivity headroom against downstream branch breakers without oversizing the frame. Breaking capacity sits at 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 9 kA at 690 V. At 690 V the 9 kA rating limits it to lower-fault systems or transformer-secondary applications. Communication function is present. ## Thermal derating and power dissipation Current rating is temperature-dependent: 630 A at 40 °C, 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. Maximum power loss is 162 W. That's the heat the breaker dumps into the enclosure at full rated current — factor it into your panel thermal calculation, especially in a sealed or high-density cabinet. The storage minimum is the handling limit, not the running limit. Dimensions: 248 mm height, 138 mm width, 110 mm depth. That depth (110 mm) is the body only — add clearance for wiring, arc chute exhaust, and the rotary handle if used. The SENTRON 3VA series uses the same drilling pattern as the previous 3VL series, so retrofitting into an existing panel usually requires no new holes.","metaTitle":"Siemens 3VA2463-5JQ32-0JH0 SENTRON MCCB, 630 A, 3-Pole, Line","metaDescription":"Siemens 3VA2463-5JQ32-0JH0 SENTRON molded case circuit breaker, 630 A at 40 °C, 3-pole, 187 kA at 240 V.
