The Siemens 3VA1110-6EF32-0AA0-ZD00 is a 3-pole IEC frame 160 molded case circuit breaker with a breaking capacity class H rating of 70kA at 415V. It uses a TM240 thermal-magnetic trip unit, set for line protection with an In of 100A, adjustable overload Ir from 70A to 100A, and short-circuit pickup Ii adjustable from 5 to 10 times In. The suffix ZD00 indicates a nut keeper kit included, configured for a DC Power OEM application in China.
The nut keeper kit on the ZD00 variant simplifies captive hardware handling during OEM panel assembly — a detail that matters when the breaker is installed in a DC power cabinet where fastener retention is critical during transport and vibration.
