The Siemens 3VA1116-5GD42-0AA0-ZD00 is a 4-pole IEC frame 160 molded case circuit breaker with a 160 A continuous current rating and a short-circuit breaking capacity (Icu) of 55 kA at 415 V AC, placing it in breaking capacity class M. The thermal-magnetic trip unit (TM210) provides fixed overload protection at Ir = 160 A and fixed short-circuit protection at Ii = 10 × In, meaning the magnetic trip activates at 1600 A. The neutral conductor is protected at 100% of the phase rating.
Deployment Context
As a panel-mounted IEC frame breaker, this unit is sized for main or feeder protection in distribution boards and motor control centers where a 160 A continuous load and a fault current capability of 55 kA at 415 V are specified. The nut keeper kit included with this variant is intended for DC Power OEM applications in China, so verify the mounting hardware matches your enclosure's bus-bar or cable termination scheme.
