It carries the ETU560 electronic trip unit, configurable for line protection, with an adjustable N-conductor protection setting (OFF, 20 % to 160 %). The interrupting capacity hits 187 kA at 240 V AC and 121 kA at 415 V and 440 V AC, so it handles high-fault utility feeds without cascading upstream breakers. ## Sizing and coordination for panel builders Communication function is built in, so it can integrate with energy management or remote-trip monitoring systems without an add-on module.","metaTitle":"Siemens 3VA2110-5JQ42-0AA0 SENTRON MCCB, 100 A, 4-Pole, ETU5","metaDescription":"Siemens SENTRON 3VA2110-5JQ42-0AA0 molded case circuit breaker, 100 A, 4-pole, ETU560 release, 187 kA at 240 V.
