The Siemens 3VA1196-6EF32-0DC0 is a SENTRON molded case circuit breaker (MCCB) rated for line protection, 3-pole, 16 A at 40 °C, with a breaking capacity of 220 kA at 240 V. That 220 kA rating means it can safely interrupt a fault current up to that level without upstream coordination issues — a high-interrupting-capacity (HIC) frame for high-fault locations like substation feeders or large motor control centers. It carries an undervoltage release (UVR) and two HQ auxiliary switches, so it's ready for remote status and shunt-trip control out of the box.
Rated current and thermal derating
The 16 A rating holds flat from 40 °C to 55 °C, then derates to 15 A at 60 °C through 70 °C. That's a clean thermal curve — no surprise drop at 50 °C, so it fits standard 40 °C panel designs without oversizing. The insulation voltage is rated 800 V, covering 480/600 V systems with margin.
Breaking capacity across voltage
Breaking capacity drops from 220 kA at 240 V to 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V and 690 V. The steep fall above 480 V means this frame is best suited for 240/415 V distribution — at 500 V it's still adequate for most industrial loads, but not for high-fault 690 V service.
Dimensions and panel fit
The MCCB measures 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole SENTRON 3VA footprint. It mounts on a DIN rail or directly to a backplate. The 76.2 mm width (3 inches) is the same as other 3VA 3-pole breakers, so it swaps into an existing panel layout without re-spacing.
Auxiliary and release configuration
This variant includes an undervoltage release (UVR) and two HQ auxiliary switches. The UVR trips the breaker when control voltage drops below a threshold — common for emergency-stop circuits or undervoltage protection on motor feeders. The two auxiliary switches provide independent NO/NC status contacts for PLC or indication. No communication function or ground-fault monitoring on this version.
