It is a 4-pole unit designed for DIN-rail or screw-mount installation in a distribution board or enclosure. ## Trip unit and protection features The ETU330 electronic trip unit provides adjustable long-time (tr) from 0.5 to 17 s, and supports ground-fault monitoring via summation current on L+N. N-conductor protection is adjustable OFF or 100%. No communication function is built in.","metaTitle":"Siemens 3VA2140-5HM46-0AA0 SENTRON MCCB, 40 A, 4-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2140-5HM46-0AA0 molded case circuit breaker, 40 A rated, 4-pole, ETU330 release. 187 kA at 240 V, 121 kA at 415 V.
