The Siemens SENTRON 3VA1110-3GE42-0AA0 MCCB is a high-performance molded case circuit breaker designed to deliver dependable overload and short-circuit protection in industrial, commercial, and infrastructure power distribution systems. As part of the globally trusted SENTRON 3VA portfolio, this MCCB combines advanced protection technology, robust construction, and exceptional operational reliability, making it a preferred choice for electrical professionals worldwide. Siemens positions the SENTRON range as a comprehensive low-voltage power distribution solution focused on safety, reliability, and efficiency.
The 3VA1110-3GE42-0AA0 features a 100A rated current, 4-pole configuration, Frame Size 160, and 25kA breaking capacity at 415V AC. It is equipped with a TM220 Thermal Magnetic Trip Unit utilizing ATFM (Adjustable Thermal Fixed Magnetic) technology. The breaker provides adjustable overload protection from 70A to 100A and fixed short-circuit protection at 10 × In, ensuring comprehensive circuit protection for critical electrical systems.
In modern electrical installations, protection devices must respond rapidly to abnormal operating conditions while ensuring continuity of operations. The Siemens 3VA1110-3GE42-0AA0 MCCB continuously monitors electrical current and automatically interrupts the circuit when overloads or short circuits occur. This helps protect motors, transformers, cables, switchgear assemblies, control panels, and other valuable electrical assets from costly damage and downtime.
The integrated thermal magnetic trip unit combines two critical protection mechanisms. The thermal element protects against sustained overload conditions, while the magnetic element reacts instantly to short-circuit faults. This dual-protection system ensures enhanced equipment safety, improved system reliability, and optimal fault coordination across industrial power networks.
Designed according to Siemens' stringent engineering standards, the 3VA1110-3GE42-0AA0 MCCB offers compact dimensions, reliable switching performance, and long service life. Its Frame Size 160 construction enables easy integration into LT panels, PCC panels, MCC panels, switchboards, distribution boards, motor control centers, and OEM equipment without occupying excessive panel space.
