What this MCCB delivers for a panel build
The Siemens SENTRON 3VA1196-6EF32-0BC0 is a 3-pole molded case circuit breaker (MCCB) rated 16 A continuous, with a breaking capacity of 220 kA at 240 V AC and 154 kA at 415 V AC — high enough for most industrial main or feeder applications where fault current is substantial. Rated current holds at 16 A from 40 °C up to 55 °C, then derates to 15 A at 60 °C and above — useful to know if the breaker sits in a warm enclosure or near other heat sources. It carries an undervoltage release (UVR) as standard, so it can trip on loss of control voltage — a common requirement for emergency-stop circuits or safety-related disconnects. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — fits standard SENTRON panel cutouts and busbar systems.
