Siemens 3VA1196-4EF36-0BC0 — SENTRON MCCB for Line Protection
The Siemens 3VA1196-4EF36-0BC0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection in distribution panels. 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. Rated insulation voltage is 800 V, and maximum power loss is 13.1 W. The breaker ships with an undervoltage release (UVR) and two auxiliary switches (HQ design) pre-installed — that saves a panel-builder a separate wiring step for remote status or shunt-trip monitoring.
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. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. No communication function or ground-fault monitoring is built in — this is a straight thermal-magnetic line-protection breaker, not a power-monitoring device.
