The Siemens 3VA1196-3EF32-0CA0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated for line protection, with a continuous current of 16 A across ambient temperatures from 40 °C to 55 °C, derating to 15 A at 60 °C through 70 °C. Its interrupting capacity is 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V — numbers that define the available fault current it can safely clear at the point of installation.
Built-in undervoltage release for coordinated protection
The UVR is factory-integrated, so there's no separate module to mount or wire inside the panel; it's a single order-code solution for applications requiring undervoltage protection per NEC 430.74 or IEC 60947-2.
At 70 mm deep, 76.2 mm wide, and 130 mm tall, this MCCB fits standard SENTRON 3VA mounting footprints and drops into existing panel layouts without re-drilling or bus-bar rework. The 3-pole design with 16 A continuous rating and integrated UVR makes it a direct replacement for earlier 3VA1 frame breakers in retrofit applications, provided the existing bus system supports the 76.2 mm pole spacing.
Thermal-magnetic trip and power dissipation
Maximum power loss is 13.1 W per pole, which matters for enclosure heat-load calculations when multiple breakers are ganged in a sealed panel.
