Four width units (72 mm wide) on the DIN rail, 76 mm deep, installable in any mounting position. ## Environmental and application notes Rated for railway applications per the design code, with a -40 to +70 °C ambient range and -40 to +75 °C storage. Energy limiting class 3 means it lets through less let-through energy (I²t) than class 1 or 2 breakers, which helps protect downstream components during a fault. Overvoltage category III suits it for fixed installation downstream of the utility meter.","metaTitle":"Siemens 5SY4463-6CC11 SENTRON MCB, 63 A 4P B-curve, 10 kA","metaDescription":"Siemens 5SY4463-6CC11 SENTRON miniature circuit breaker, 63 A, 4-pole, B characteristic, 10 kA breaking capacity per EN 60898.
