The Siemens 3VA1196-6EF32-0CH0 is a 3-pole IEC frame 160 molded case circuit breaker with a 16 A thermal-magnetic trip unit (TM240, ATAM) and a 70 kA interrupting rating at 415 V AC — breaking capacity class H.
The TM240 thermal-magnetic trip provides adjustable overload protection (Ir = 11...16 A, set via a dial) and fixed magnetic short-circuit pickup (Ii = 10...20 x In, so 160...320 A). The UVR drops the breaker on loss of control voltage, standard for emergency-stop or undervoltage protection schemes.
Deployment context
The nut keeper kit secures the line-side lug fasteners, preventing loosening under vibration — a practical detail for panel builders shipping assembled gear.
