The breaker carries 187 kA breaking capacity at 240 V, tapering to 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V — so at common 400 V-class distribution voltages it still clears 121 kA, which covers most industrial service-entrance and subfeed applications. The 63 A rating holds flat from 40 °C through 50 °C, then drops to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. The breaker body is 76.2 mm wide, 130 mm tall, 70 mm deep — standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration. Two HP auxiliary switches are built in (design of the auxiliary switch: 2 auxiliary switches HP), so you get position feedback without an add-on module.","metaTitle":"Siemens 3VA1163-5EE32-0AB0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1163-5EE32-0AB0 molded case circuit breaker, 63 A rated at 40 °C, 3-pole, breaking capacity 187 kA at 240 V.
