Rated In is 1000 A, with overload protection (Ir) adjustable from 400 A to 1000 A, short-time pickup (Isd) from 0.6 to 10× In, and instantaneous (Ii) from 1.5 to 10× In. Ground-fault pickup (Ig) is adjustable from 0.2 to 1× In with a time delay (tg) of 0.05–0.8 s, and can be switched off entirely. The neutral conductor protection is also adjustable from OFF up to 100% of the phase setting. A universal release (24 V DC) is built in, plus two HQ auxiliary switches, one HQ trip alarm switch, and one HQ electrical alarm switch — all factory-fitted. The ETU860's LSIG profile gives you full selectivity coordination with downstream feeders: the short-time and ground-fault bands are adjustable independently, so you can set the time-current curve to ride through motor inrush and still trip on a bolted fault. The four-pole construction with adjustable N protection makes it suitable for TN-S or TN-C-S systems where the neutral needs to be switched and protected separately. The 24 V DC universal release lets you integrate a shunt trip from a remote emergency-stop or fire-alarm panel without an additional interposing relay.","metaTitle":"Siemens 3VA2510-5KQ42-0LL0 Circuit Breaker, 1000A, 55kA @ 41","metaDescription":"Siemens 3VA2510-5KQ42-0LL0 IEC frame 1000 breaker, 4-pole, ETU860 LSIG, 55kA Icu @ 415V.
