Breaking capacity runs from 121 kA at 240 V down to 11.9 kA at 690 V — that 121 kA figure at 240 V covers high-fault utility feeds common in North American commercial and light industrial panels. At 415 V (typical European distribution) it still handles 75.6 kA, giving solid selectivity headroom downstream. The 3VA1 frame measures 130 mm high × 76.2 mm wide × 70 mm deep. Width is 3 in. Maximum power dissipation is 17.3 W. ## Comparison with 3VA1110-5ED36-0AC0 The 3VA1110-5ED36-0AC0 is a smaller-frame SENTRON MCCB with electronic release and no shunt trip. The 3VA1163-4EF32-0KA0 carries the shunt trip (STL) as standard. The 3VA1110 frame is physically larger.","metaTitle":"Siemens 3VA1163-4EF32-0KA0 SENTRON MCCB, 63A, 3-Pole, 70 mm","metaDescription":"Siemens 3VA1163-4EF32-0KA0 SENTRON molded case circuit breaker, 63 A at 40 °C, 3-pole, 121 kA at 240 V.
