It's built for high-fault panels: interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and still holds 75.6 kA at 440 V — numbers that tell you this breaker is sized for transformer secondaries or large motor control centers where fault current runs hot. The shunt trip release (3VA9688-0BL33) is integrated, and the auxiliary contact block gives you 2 auxiliary switches plus a separate trip alarm switch — enough for remote status and fault annunciation without stacking add-ons. ## Thermal derating — what the 63 A rating really means at panel temperature The 63 A rating holds flat from 40 °C through 50 °C, then starts a gentle roll-off: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON distribution blocks and panel-mount kits.","metaTitle":"Siemens 3VA1163-5ED32-0KH0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1163-5ED32-0KH0 molded case circuit breaker, 3-pole, 63 A rated, 187 kA interrupting at 240 V.
