Breaking capacity hits 187 kA at 240 V and still clears 121 kA at 415 V and 440 V. That's serious fault-interruption muscle for a 63 A frame. This breaker ships with the ETU860 electronic overcurrent release — that's the programmable one, not a fixed thermal-magnetic. You get adjustable long-time pickup and delay (tr from 0.5 to 25 s), short-time, instantaneous, and ground-fault protection via summation of L+N conductors. The N-conductor protection is adjustable OFF or from 40 % to 160 %. For a site electrical engineer building a selective coordination study, the ETU860 gives you the curve-shaping headroom to stay coordinated downstream without oversizing the main. IP40 on the front face means it's splash-resistant from the operator side but not sealed for washdown; keep it inside the panel or behind a door.","metaTitle":"Siemens 3VA2163-5KQ46-0AA0 SENTRON MCCB, 63 A, 4-Pole, 187 k","metaDescription":"Siemens 3VA2163-5KQ46-0AA0 SENTRON molded case circuit breaker, 63 A continuous, 4 poles, 187 kA breaking at 240 V.
