Siemens 3VA1196-4EF36-0BC0 — SENTRON MCCB for Line Protection
It carries a continuous current rating of 16 A across ambient temperatures from 40 °C to 55 °C, derating to 15 A at 60 °C through 70 °C — so in a warm enclosure you lose 1 A of headroom above 55 °C. This is a 3-pole unit with an interrupting capacity of 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. At 415 V — common for industrial motor feeders — the 75.6 kA SCCR gives substantial fault-clearing headroom for most low-voltage switchgear lineups.
Panel Fit & Integration Notes
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard SENTRON 3VA frame that fits Siemens distribution panels and most third-party enclosures with DIN-rail or screw-mount provisions. The 70 mm depth means it clears shallow backpanels where a deeper MCCB would conflict with wiring ducts or rear-mounted busbars.
