The interrupting capacity is 187 kA at 240 V, stepping down to 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V — this is a high-breaking-capacity device sized for fault currents on large distribution transformers or close-coupled switchgear. The UVR means the breaker trips when control voltage drops, which is standard for emergency-stop or safety-related disconnect circuits. The breaker measures 130 mm tall, 76.2 mm wide, and 70 mm deep — a 3-pole frame that fits standard Siemens 3VA1 panel footprints and busbar systems. Depth of 70 mm means it clears most gland plates and backpanel wiring ducts without interference. The 3VA1 series uses screw-clamp terminals; wire range and torque values are on the nameplate.","metaTitle":"Siemens 3VA1163-5EF32-0CH0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens 3VA1163-5EF32-0CH0 SENTRON 3-pole molded case circuit breaker, 63 A rated at 40 °C, 187 kA breaking capacity at 240 V.
