The ETU860 trip unit gives you LSIG protection: long-time (overload), short-time, instantaneous, and ground-fault, all programmable. Overload protection (Ir) is adjustable from 250 A to 630 A, short-time pickup (Isd) from 0.6 to 9× In, and instantaneous pickup (Ii) from 1.5 to 9× In. Ground-fault protection can be switched off; when active, Ig adjusts from 0.2 to 1× In with a time delay tg from 0.05 to 0.8 s. Neutral protection is optional via an external current transformer, up to 160% of In. ## Built-in accessories and control voltage All auxiliary contacts are wired and ready; no separate order for a signal block. For an integrator: verify the shunt trip coil matches your control transformer tap before commissioning — 208 V and 277 V are different taps on a 480 V delta-to-wye transformer.","metaTitle":"Siemens 3VA2463-6KQ32-0KL0 Circuit Breaker, 85kA @ 415V, 630","metaDescription":"Siemens 3VA2463-6KQ32-0KL0 IEC frame 630 circuit breaker, 85kA breaking capacity at 415V, 3-pole, ETU860 LSIG protection, 630A.
