The Siemens 3VA1196-6EF32-0AG0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection, carrying a continuous current rating of 16 A at 40 °C and derating to 15 A at 70 °C. Its interrupting capacity hits 220 kA at 240 V, 154 kA at 415 V, and still holds 17 kA at 690 V — meaning it can clear a bolted fault on a 480 V distribution bus without upstream coordination headaches.
Interrupting & continuous ratings
Three-pole construction with a TM240 thermal-magnetic release. The 16 A frame holds steady across 40–55 °C ambient, then drops to 15 A at 60–70 °C — that derating curve matters if this breaker sits in a crowded, hot panel. Interrupting capacity falls off as voltage climbs: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, then a sharp drop to 17 kA at 500 V and 690 V.
