The Siemens SENTRON 3VA1110-3GE42-0AA0 MCCB is a high-performance molded case circuit breaker designed to provide dependable overload and short-circuit protection for modern industrial, commercial, and infrastructure power distribution systems. As a part of the globally trusted SENTRON 3VA family, this MCCB combines Siemens engineering excellence with advanced thermal magnetic trip technology to ensure superior protection, operational safety, and long-term reliability. The breaker features a 100A rated current, 4-pole configuration, 25kA breaking capacity at 415V AC, and a TM220 Adjustable Thermal Fixed Magnetic (ATFM) Trip Unit, making it ideal for demanding electrical protection applications.
Electrical systems are constantly exposed to overload conditions, short circuits, and unexpected fault currents that can damage equipment and disrupt operations. The Siemens 3VA1110-3GE42-0AA0 continuously monitors current flow and automatically disconnects the circuit whenever abnormal operating conditions occur. This helps protect motors, transformers, switchgear assemblies, cables, distribution panels, and critical electrical infrastructure from costly failures and downtime. The SENTRON 3VA range is specifically developed for low-voltage power distribution and industrial protection applications.
One of the key advantages of the 3VA1110-3GE42-0AA0 MCCB is its TM220 Thermal Magnetic Trip Unit featuring ATFM (Adjustable Thermal Fixed Magnetic) technology. The overload protection setting can be adjusted from 70A to 100A, allowing better coordination with connected equipment and electrical loads. The fixed magnetic protection responds instantly during short-circuit events, ensuring rapid fault clearance and enhanced safety.
Designed with a compact Frame Size 160, this MCCB offers easy installation in LT panels, PCC panels, MCC panels, switchgear assemblies, motor control centers, and OEM equipment. Its rugged industrial-grade construction ensures excellent durability, high switching reliability, and a long operational lifespan even in demanding environments.
