The Siemens SENTRON 3VA1196-4EF32-0AG0 is a 3-pole molded case circuit breaker (MCCB) rated for 16 A continuous current across ambient temperatures from 40 °C up to 55 °C, derating to 15 A at 60 °C through 70 °C. Breaking capacity is the headline number here: 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.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard SENTRON 3VA form factor that fits the usual DIN-rail or screw-mount patterns in distribution boards. The breaker ships with one auxiliary switch and one trip alarm switch (HP design) factory-fitted, so you get remote status indication without ordering separate accessories. The trip indicator is present, so a visual check confirms the breaker has tripped on fault rather than being manually switched off.
