The Siemens 3VA1116-6GF42-0AA0-ZD00 is a 4-pole IEC frame 160 molded case circuit breaker with a 70 kA interrupting capacity at 415 V — that's breaking capacity class H, meaning it clears high-fault currents without upstream coordination issues in industrial distribution panels. It carries a TM240 thermal-magnetic trip unit with overload protection adjustable from 112 A to 160 A and short-circuit pickup set at 5 to 10 times the rated current In=160 A, plus 100% neutral conductor protection.
Integration and Deployment
Mounts on standard DIN rail in a panel enclosure. The 4-pole footprint occupies the full width of a typical IEC distribution board; account for the nut keeper kit (included for DC Power OEM in China) when planning gland-plate clearance.
