Its ETU850 electronic trip unit delivers interrupting ratings of 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V — the 330 kA figure at 240 V is the headline for high-fault utility or transformer-fed panels. The 86 mm depth, 105 mm width, and 181 mm height fit standard MCCB panel cutouts; the IP40 front-face protection suits enclosed distribution boards where dust ingress is a concern.","metaTitle":"Siemens 3VA2040-7KP32-0AA0 SENTRON MCCB, 40 A, 3-pole, ETU85","metaDescription":"Siemens SENTRON 3VA2040-7KP32-0AA0 molded case circuit breaker, 40 A, 3-pole, ETU850 release, 330 kA at 240 V.
