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. It ships fully assembled with an undervoltage release (UVR) rated 120-127 V AC 50/60 Hz, two HQ auxiliary switches, one HQ trip alarm switch, and a nut keeper kit for the line-side lugs.
What the ratings mean for your panel
The 70 kA Icu at 415 V places this in breaking capacity class H — it can safely interrupt a fault current up to 70 kA without upstream fuses or current-limiting breakers, which simplifies selectivity coordination in high-fault panels. 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
Mounts in a standard IEC distribution panel or motor control center on a DIN rail or bolted bus connection. The nut keeper kit secures the line-side lug fasteners, preventing loosening under vibration — a practical detail for panel builders shipping assembled gear.
