It carries a full-load interrupting rating of 187 kA at 240 V, stepping down to 121 kA at 415 V and 75.6 kA at 440 V — numbers that matter when you're coordinating downstream breakers and need the SCCR headroom to avoid a cascading failure. This is a line-protection design, not a motor-protection piece, so it's meant for feeder and distribution panels where you want selective coordination with smaller branch breakers. The 63 A rating holds flat across 40 °C to 50 °C, then derates smoothly to 58 A at 70 °C — so in a hot panel near a drive or transformer, you still have 58 A of continuous capacity. Dimensions are 70 mm deep, 76.2 mm wide (3 in), and 130 mm tall (5.12 in). The shunt trip adds a small footprint on the side; verify clearance for the trip unit's wiring if you're retrofitting into a tight enclosure.","metaTitle":"Siemens 3VA1163-5EE32-0KA0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1163-5EE32-0KA0 molded case circuit breaker, 63 A at 40 °C, 3-pole, interrupting rating 187 kA at 240 V.
