Siemens SENTRON 3VA Adapter Frame 8GB4562 for 3VA1/3VA2 100-250A to 400/630A Cutout

The Siemens 8GB4562 adapter frame is a specialized mounting solution that bridges the gap between smaller SENTRON 3VA circuit breakers and larger panel cutouts. Unlike generic adapter plates, this frame is engineered specifically for the 3VA series, allowing a 3VA1 or 3VA2 breaker with frame sizes 100A, 160A, or 250A to be securely installed into a cutout originally sized for a 400A or 630A breaker. This eliminates the need for custom panel modifications and speeds up retrofit or upgrade projects.

Highlights

• Adapts 3VA1/3VA2 breakers (100A, 160A, 250A) to 3VA2 400A/630A panel cutouts
• Front panel mounting for easy access and installation
• Industrial-grade plastic construction in black
• Complies with IEC standards for electrical distribution

In daily use

When upgrading a distribution board or replacing a breaker, the 8GB4562 ensures a clean, professional fit without leaving gaps or requiring additional fabrication. Its precise inner cutout dimensions (185 mm x 105 mm) match the smaller breaker's mounting pattern, while the outer dimensions (280 mm x 185 mm) cover the larger opening. The frame is lightweight (0.3 kg) and installs from the front, making it ideal for maintenance tasks.
