It carries an ETU350 LSI trip unit, adjustable overload protection from 250A to 630A, and short-circuit protection set at 1.5 to 9 times Ir with an instantaneous pickup of 9x In. The neutral conductor protection can be set to OFF, 50%, or 100% of phase protection. A factory-fitted shunt trip (left side, 208-277V AC / 220-250V DC) and two auxiliary switch channels are included, plus a nut keeper kit for secure mounting. The ETU350 LSI trip unit provides electronic long-time, short-time, and instantaneous protection, giving you selectivity coordination with downstream devices. The adjustable N protection (OFF, 50%, 100%) lets you match the breaker to a 4-wire system where neutral loading varies. ## Panel integration The shunt trip and auxiliary switches are pre-installed on the left side, so verify clearance for wiring access and any right-side accessories you may add later. The nut keeper kit simplifies torque-down on the main lugs — no loose washers to drop into a live panel.","metaTitle":"Siemens 3VA2463-6HN42-0KJ0 630A 85kA @ 415V 4-Pole Breaker","metaDescription":"Siemens 3VA2463-6HN42-0KJ0 circuit breaker, IEC frame 630, class H Icu=85kA @ 415V, 4-pole, ETU350 LSI protection, In=630A, shunt trip 208-277V AC.
