SENTRON 3VA1 MCCB — 16 A, 3-Pole, Line Protection with UVR
The Siemens 3VA1196-5EF36-0DA0 is a SENTRON 3VA1 molded case circuit breaker (MCCB) designed for line protection in distribution panels. It carries a continuous current rating of 16 A at 40 °C, derating to 15 A at 60 °C and above — the thermal curve stays flat through 55 °C, so no derating penalty in a typical 50 °C panel ambient. Three-pole configuration, fitted with a TM240 thermal-magnetic release. The integrated undervoltage release (UVR) trips the breaker on loss of control voltage — standard for safety circuits where a downstream contactor or safety relay needs to drop the load on undervoltage. Breaking capacity is the headline here: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and still 17 kA at 500 V and 690 V. That 187 kA at 240 V is well above typical utility fault levels in North American 240/120 V split-phase panels — you are buying headroom for high-fault installations.
Panel Fit and Mounting
Width 76.2 mm (3 in), depth 70 mm, height 130 mm. Standard 3-pole MCCB footprint. Rated insulation voltage 800 V, so it can sit in a 690 V distribution bus without derating the insulation path. Power dissipation 13.1 W max — account for that in the enclosure thermal budget if you are packing multiple breakers in a sealed cabinet.
