What this breaker delivers
The Siemens SENTRON 3VA2216-6KP42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for 160 A continuous current (Iu) across the full ambient range from 40 °C to 70 °C — no derating needed up to the top of that band. Its interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4.5 kA at 690 V — so the SCCR headroom is there for high-fault industrial distribution panels, not just light commercial mains. The ETU850 electronic trip unit gives you adjustable N-conductor protection (OFF, 20 % to 160 % of Iu) and onboard communication, which means this breaker talks to the plant monitoring system without an add-on module.
Panel fit and integration
Dimensions are 86 mm deep, 140 mm wide, 181 mm tall — a standard 4-pole MCCB footprint for DIN-rail or panel-mount enclosures. IP40 on the front face keeps dust out of the trip-unit compartment in a clean indoor panel. Rated insulation voltage Ui is 800 V. Storage range -40 °C to 80 °C; operating range -25 °C to 70 °C.
