The Siemens SENTRON 3VA1110-3GE42-0AA0 MCCB is a high-performance molded case circuit breaker engineered to provide dependable protection against overloads, short circuits, and electrical faults in industrial, commercial, and infrastructure power distribution systems. As part of the globally trusted SENTRON 3VA series, this MCCB combines advanced protection technology, compact design, and Siemens engineering excellence to ensure safe and uninterrupted operation of critical electrical networks. The breaker features a 100A rated current, 4-pole configuration, and 25kA breaking capacity at 415V AC, making it ideal for demanding low-voltage power distribution applications.
The 3VA1110-3GE42-0AA0 is equipped with a TM220 Thermal Magnetic Trip Unit featuring ATFM (Adjustable Thermal Fixed Magnetic) technology. This advanced protection system provides adjustable overload protection from 70A to 100A and fixed magnetic short-circuit protection at 10 × In. This combination ensures accurate overload protection while delivering rapid fault interruption during short-circuit conditions, helping safeguard motors, transformers, switchgear assemblies, cables, and distribution panels.
In modern industrial environments, electrical systems face continuous exposure to fluctuating loads, overload conditions, and fault currents. The Siemens 3VA1110-3GE42-0AA0 MCCB continuously monitors current flow and automatically disconnects the circuit whenever abnormal operating conditions occur. This proactive protection minimizes equipment damage, reduces maintenance costs, and improves overall system reliability. The SENTRON 3VA range has been specifically developed for low-voltage power distribution applications where operational continuity and safety are critical.
Built on Frame Size 160, the Siemens 3VA1110-3GE42-0AA0 offers a compact footprint that simplifies installation within LT panels, MCC panels, PCC panels, switchboards, motor control centers, and OEM machinery. Its rugged industrial-grade construction ensures long service life, reliable switching performance, and excellent endurance under demanding operating conditions.
