The Siemens SENTRON 3VA1110-3EE36-0AA0 molded case circuit breaker is a 3-pole line protection device designed for dependable overcurrent and short-circuit protection in industrial low-voltage distribution systems. Featuring frame size 160, breaking capacity class N, and Icu of 25 kA at 415 V AC, this MCCB delivers consistent performance in demanding electrical environments. Its TM220 thermal-magnetic release provides overload protection (Ir 70–100 A) and fixed short-circuit protection at 10× In, ensuring stable protection across operational conditions.
According to the Siemens technical data, the 3VA1110-3EE36-0AA0 supports rated operational voltages up to 690 V AC and 500 V DC, with an insulation voltage of 800 V. It offers a mechanical service life of 20,000 operating cycles and electrical endurance of up to 9,000 cycles at 380/415 V AC. With a front terminal design, box terminals on both sides, and compatibility with conductor sizes up to 70 mm² (stranded), this MCCB is well suited for structured panel installations in heavy-duty electrical networks.
The breaker supports optional motor-drive accessories and includes IP40 protection on the front. Operational temperature ranges from -25°C to +70°C, making it suitable for industrial, utility, and commercial applications.
