It carries an ETU560 electronic trip unit configured for LSIG protection — long-time (Ir adjustable 200-500A), short-time (Isd 0.6-10x In), instantaneous (Ii 1.5-14x In), and ground-fault (Ig 0.2-1x In, tg 0.05-0.8s). The shunt trip (STL) operates on 220-250V DC or 208-277V AC. This is a line-protection breaker sized for a 500A continuous load (In=500A) with the overload pickup set via the ETU's rotary dials. The ETU560 LSIG trip unit gives you full selectivity: you can coordinate the long-time pickup (Ir) anywhere from 200 to 500 A, and the short-time delay (tsd) lets you ride through downstream faults so only the closest breaker opens. The ground-fault element (Ig) is adjustable from 20% to 100% of In with a time delay of 0.05 to 0.8 seconds, making it suitable for equipment protection or, with the right setting, personnel protection in grounded systems. The shunt trip (STL) accepts either 220-250V DC or 208-277V AC control voltage — verify your control supply matches before wiring. The ETU560 display and pushbuttons are front-accessible for setting adjustments without removing the cover. The shunt trip occupies the accessory slot on the left side; a nut keeper kit is included for secure terminal fastening. For N-conductor protection, an external current transformer can be added (up to 160% of In). Plan for adequate bending radius on the incoming and outgoing cables — at 500A continuous, you are looking at paralleled conductors or large single cables.","metaTitle":"Siemens 3VA2450-6JQ32-0KA0 Circuit Breaker, 500A ETU560 LSIG","metaDescription":"Siemens 3VA2450-6JQ32-0KA0 IEC frame 630 breaker, 85kA @ 415V, 3-pole, ETU560 LSIG, In=500A.
