The maximum power loss is 10 W, which is modest for a 4-pole 100 A frame and won't drive significant heat buildup in a well-ventilated enclosure. ## What the ETU340 trip unit does for you The ETU340 is an electronic overcurrent release with LSI protection: long-time (overload), short-time (short-circuit with delay), and instantaneous. The short-time delay lets you coordinate with downstream breakers for selective tripping — a fault on a branch feeder clears the branch breaker first, not the main. No ground-fault monitoring is built in, so if you need GF protection, you'll add an external module or specify the GF variant.","metaTitle":"Siemens 3VA2110-6HK42-0AA0 SENTRON MCCB, 100 A, 4-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2110-6HK42-0AA0 molded case circuit breaker, 100 A continuous, 4-pole, ETU340 electronic trip unit, 242 kA at 240 V.
