The Siemens SENTRON 3VA1110-3GE42-0AA0 MCCB is a premium molded case circuit breaker engineered to deliver dependable protection against overloads, short circuits, and electrical faults in industrial, commercial, and infrastructure power distribution systems. Designed within Siemens' globally trusted SENTRON 3VA Series, this MCCB combines advanced protection technology, compact dimensions, and exceptional reliability to safeguard critical electrical assets and ensure uninterrupted operations.
The 3VA1110-3GE42-0AA0 features a 100A rated current, 4-pole configuration, Frame Size 160, and 25kA breaking capacity at 415V AC. Equipped with a TM220 Thermal Magnetic Trip Unit (ATFM – Adjustable Thermal Fixed Magnetic), it provides adjustable overload protection from 70A to 100A and fixed magnetic short-circuit protection at 10 × In, ensuring comprehensive protection for low-voltage power distribution systems.
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 interrupts the circuit whenever abnormal operating conditions occur. This proactive protection minimizes equipment damage, reduces maintenance costs, and helps maintain operational continuity across manufacturing plants, utilities, commercial facilities, and infrastructure projects.
The integrated ATFM Thermal Magnetic Trip Unit combines two essential protection mechanisms. The thermal element protects against sustained overloads, while the magnetic element provides instantaneous response to short-circuit faults. This combination ensures rapid fault clearance, enhanced personnel safety, and reliable protection for motors, transformers, cables, switchgear assemblies, and power distribution equipment.
Built according to Siemens' stringent engineering standards, the 3VA1110-3GE42-0AA0 MCCB offers a mechanical endurance of up to 20,000 operating cycles, high electrical durability, and dependable switching performance. Its compact design simplifies installation in LT panels, MCC panels, PCC panels, switchboards, and OEM equipment while maintaining superior protection capabilities.
