Siemens SENTRON 3VA1196-6EF32-0CA0 — 16 A MCCB with UVR, 220 kA at 240 V
The Siemens SENTRON 3VA1196-6EF32-0CA0 is a 3-pole molded case circuit breaker (MCCB) rated for 16 A continuous current at 40 °C, with a TM240 thermal-magnetic overcurrent release and an integrated undervoltage release (UVR). Its interrupting rating reaches 220 kA at 240 VAC, 154 kA at 415 VAC, and 121 kA at 440 VAC — figures that place it squarely in high-fault-duty distribution panels where upstream transformer capacity or parallel-feed sources drive available fault current above 100 kA. Rated insulation voltage is 800 V. The TM240 release provides fixed thermal and magnetic trip settings calibrated for line protection (cable and busbar), not motor overload — this is a distribution breaker, not a motor circuit protector.
Mounting and integration — panel fit
Dimensions are 130 mm height, 76.2 mm width, and 70 mm depth — a standard SENTRON 3VA1 frame size that mounts via screw terminals to a backplate or DIN rail adapter. The 3-pole block occupies roughly 3 inches of panel width; plan for bending-radius clearance on the line and load lugs, particularly when routing 16 A branch circuits in a crowded enclosure. Operating temperature range is -25 °C to 70 °C, with full 16 A rating maintained up to 55 °C; above that, derate to 15 A at 60–70 °C.
Lifecycle and sourcing
The breaker ships with the undervoltage release factory-installed (design designation UVR), so no field-fit kit is required for that function.
