The Siemens 3VA2216-7JP32-0AH0 is a 3-pole IEC frame 250 molded case circuit breaker rated for 160 A continuous current, with a class C breaking capacity of 110 kA at 415 V AC. It carries the ETU550 electronic trip unit configured for LSI protection (long-time, short-time, instantaneous). Overload protection (Ir) is adjustable from 63 A to 160 A; short-time pickup (Isd) spans 0.6–10× In; instantaneous (Ii) covers 1.5–12× In. The breaker ships with a 2-pole auxiliary switch changeover and a separate trip alarm changeover contact.
Mounts in a standard IEC 60947-2 panelboard or distribution enclosure on the DIN-rail or screw-fixed chassis. The ETU550 is line-powered — no external control voltage needed for the trip unit. The auxiliary and alarm contacts are pre-wired to the terminal block; confirm the changeover wiring matches your PLC or status-indication circuit before closing the breaker. Neutral conductor protection is available as an option with an external current transformer, up to 160 % of the phase rating.
