The Siemens SENTRON 3VA1110-3GE42-0AA0 MCCB is a high-performance molded case circuit breaker engineered to provide superior protection against overloads, short circuits, and electrical faults in low-voltage power distribution systems. Designed as part of the globally trusted SENTRON 3VA Series, this MCCB combines Siemens engineering excellence with advanced thermal magnetic trip technology to ensure maximum safety, operational continuity, and equipment protection. The breaker features a 100A rated current, 4-pole configuration, and 25kA breaking capacity at 415V AC, making it an ideal choice for industrial, commercial, and infrastructure applications.
The 3VA1110-3GE42-0AA0 is equipped with a TM220 Thermal Magnetic Trip Unit utilizing ATFM (Adjustable Thermal Fixed Magnetic) technology. This advanced protection system offers adjustable overload protection from 70A to 100A while providing fixed magnetic short-circuit protection at 10 × In. The result is accurate fault detection, rapid circuit interruption, and enhanced protection for motors, transformers, switchgear assemblies, cables, and critical electrical infrastructure.
Modern industrial facilities demand reliable electrical protection systems capable of preventing costly downtime and equipment damage. The Siemens 3VA1110-3GE42-0AA0 MCCB continuously monitors current flow and automatically disconnects the circuit whenever abnormal conditions are detected. This proactive approach significantly improves electrical safety, reduces maintenance costs, and enhances the lifespan of connected equipment.
The compact Frame Size 160 design allows seamless integration into LT panels, MCC panels, PCC panels, distribution boards, switchgear assemblies, and OEM machinery. Built to Siemens' stringent quality standards, this MCCB delivers exceptional durability, high switching reliability, and long-term operational performance even in demanding industrial environments.
