The Siemens 3VA1010-4ED32-0AA0-ZD00 is a 3VA1 IEC frame 100 molded-case circuit breaker, 3-pole, rated In=100A with a breaking capacity class S delivering Icu=36kA at 415V. The TM210 thermal-magnetic trip unit gives fixed overload protection at Ir=100A and fixed short-circuit protection at Ii=10 x In (1000A). The FTFM designation indicates it's a fixed, non-interchangeable trip — what you order is what you get; no field trip-unit swaps.
The fixed Ir=100A and Ii=10 x In (1000A magnetic pickup) suit this breaker for a feeder or large branch circuit where the load current is stable and known — a motor control center feeder, a distribution panel main, or a dedicated load like a 100A-rated compressor or pump. The 3-pole configuration covers three-phase systems. The nut keeper kit (included for the DC Power OEM variant) adds a mechanical anti-vibration feature for the line-side lugs — useful in high-vibration environments like near large contactors or drives.
Molded-case circuit breakers in the 3VA1 frame (100A frame size) are standard in industrial control panels, switchboards, and motor control centers. They mount on DIN rail or bolt directly to a busbar system. The 3-pole design fits three-phase power distribution. The fixed trip means no field adjustment — specify the exact overload and short-circuit settings at order time, which this code does.
