Communication function is built in, so this breaker talks to your control system without an add-on module. Breaking capacity is the headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. The 5.4 W maximum power loss is low enough that you can pack several of these in a row without thermal worry. Mounting is screw-fixed to the backplate, not DIN-rail, so plan for drilled and tapped holes or a mounting plate. The SENTRON series carries IEC 60947-2 certification for molded case circuit breakers. The product designation is line protection, meaning it's intended for feeder and main breaker duty, not motor circuit protection (that would be a different trip curve).","metaTitle":"Siemens 3VA2063-5KQ46-0AA0 SENTRON MCCB, 63 A, 4-Pole, ETU86","metaDescription":"Siemens SENTRON 3VA2063-5KQ46-0AA0 molded case circuit breaker, 63 A, 4-pole, ETU860 trip unit, 187 kA at 240 V.
