Siemens SENTRON 3VA1196-3EF32-0DA0 — Line Protection MCCB with Undervoltage Release
The Siemens SENTRON 3VA1196-3EF32-0DA0 is a 3-pole molded case circuit breaker (MCCB) designed for line protection, carrying a 16 A continuous rating that holds flat from 40 °C through 55 °C before derating to 15 A at 65 °C and 70 °C. Its interrupting capacity reaches 75.6 kA at 240 VAC, 52.5 kA at 415 VAC, 32 kA at 440 VAC, and 11.9 kA at both 500 VAC and 690 VAC — figures that give the panel designer headroom for high-fault downstream coordination without cascading upstream. The unit ships with a factory-fitted undervoltage release (UVR) of the TM240 type, so it drops the load on loss of control voltage — a standard requirement for emergency-stop circuits and machine-guarding zones where a voltage dip must clear the power path. Rated insulation voltage is 800 V, and the operating temperature range spans -25 °C to 70 °C, with storage from -40 °C to 80 °C.
Physical Fit & Panel Integration
Dimensions are 130 mm high, 76.2 mm wide, and 70 mm deep — a standard SENTRON 3VA footprint that mounts directly onto DIN rail or a mounting plate without adapters. Maximum power loss is 13.1 W, which factors into the enclosure thermal budget when grouping several breakers in a sealed panel.
Key Functional Notes
No communication function, no ground-fault monitoring, and no trip indicator are fitted — this is a straight line-protection breaker with undervoltage release, sized for the main feed or a large subfeed where remote monitoring is handled upstream. The TM240 overcurrent release provides thermal-magnetic protection; the thermal element handles overloads, the magnetic element clears short-circuits within the rated breaking capacity.
