It carries an ETU330 electronic trip unit with adjustable long-time delay (tr min 0.5 s, tr max 17 s) and adjustable N-conductor protection (OFF or 100%). The interrupting ratings are the headline: 187 kA at 240 V, 121 kA at 415 V and at 440 V, 76 kA at 500 V, and 3 kA at 690 V. Ground fault monitoring is built in via summation current formation of L + N conductors, which saves adding an external GF relay for grounded-neutral systems. ## Trip unit and protection settings The ETU330 electronic release provides adjustable long-time pickup and delay, plus fixed short-time and instantaneous settings typical of a line-protection MCCB. The N-conductor protection can be set to OFF or 100% of the phase rating, which is useful for panels feeding mixed single-phase and three-phase loads where the neutral may carry near-phase current. Power loss is 5.4 W maximum — negligible for thermal coordination in a crowded enclosure.","metaTitle":"Siemens 3VA2063-5HM46-0AL0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2063-5HM46-0AL0 molded case circuit breaker, 63 A, 4-pole, ETU330 release, 187 kA at 240 V.
