The Siemens SENTRON 3VA2116-7JP46-0AA0 is a 4-pole molded case circuit breaker rated at a continuous current Iu of 160 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. The interrupting capacity reaches 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. That spread means this breaker handles high-fault utility feeds at low voltage and still clears moderate faults at 690 V, which is useful for industrial distribution where the service voltage varies by region or transformer tap. The electronic trip unit is an ETU550, which supports communication functions — a step up from thermal-magnetic units for selectivity coordination and remote monitoring.
The 3VA2116-7JP46-0AA0 measures 86 mm deep by 140 mm wide by 181 mm high. The 140 mm width for a 4-pole frame is standard for SENTRON 3VA breakers in this current class, so it will occupy the same DIN-rail or mounting-plate footprint as other 3VA 160 A 4-pole units. Maximum power loss is 25.5 W at rated current.
