The Siemens 3VA2463-5JP32-0KK0 is an IEC frame 630 molded-case circuit breaker in the 3VA2 series, breaking capacity class M, with a rated ultimate short-circuit breaking capacity Icu of 55 kA at 415 V AC. It is a 3-pole unit configured for line (cable/feeder) protection, fitted with an ETU550 electronic trip unit set for LSI protection — long-time (Ir adjustable 250 A to 630 A), short-time (Isd 0.6–9× In), and instantaneous (Ii 1.5–9× In). The breaker ships with a shunt trip accessory wired left-side, rated 208–277 V AC 50/60 Hz and 220–250 V DC, plus one auxiliary contact. This is a panel-mount device sized for main or large feeder duty in switchboards, MCCs, and distribution enclosures.
The ETU550 LSI trip unit gives you field-adjustable long-time pickup (Ir) from 250 A to 630 A, so a single frame covers a wide cable/load range. The shunt trip on the left side accepts either AC (208–277 V) or DC (220–250 V) control voltage, making it suitable for remote-trip schemes from a safety PLC or E-stop circuit.
