The ETU330 trip unit provides LSI (long-time, short-time, instantaneous) plus ground-fault (LIG) protection, with adjustable Ir from 25 A to 63 A and Ii from 1.5 to 12 times In. The ground-fault pickup (Ig) is adjustable between 0.25 and 1 times In, with a time delay of 0.1 or 0.3 seconds, making it suitable for selective coordination downstream. The neutral conductor protection is adjustable (OFF or 100% of phase rating) via the trip unit settings, which is useful for 4-wire systems where neutral protection is required by local code. Spring-cage or screw terminals accept standard copper conductors up to the frame rating — verify lug range against your cable size during panel build.","metaTitle":"Siemens 3VA2063-5HM42-0AH0 Circuit Breaker, 55kA @ 415V, 63A","metaDescription":"Siemens 3VA2063-5HM42-0AH0 IEC frame 100 breaker, 55kA Icu @ 415V, 4-pole, ETU330 LIG, In 63A.
