Siemens 3VA1 Motor Protection Switch 0.18-0.25A 500 VAC 6A

Siemens 3VA1 Motor Protection Switch is a compact protection device designed to safeguard small motors from overload and short-circuit conditions in control panels and machine applications. This 3VA1 model handles nominal motor currents in the 0.18–0.25 A range and supports operation up to 500 V AC, with a 6 A rating for the protected circuit. The device integrates overload protection with motor circuit switching, allowing reliable motor shutdown when abnormal current or thermal conditions are detected, helping prevent motor damage and downtime. The 3VA1 family from Siemens SENTRON is intended for panel builders and machine designers seeking compact, modular protection that can be coordinated with contactors and other motor protection devices. Typical applications include conveyors, pumps, fans, and small automation motors in packaging lines, textile equipment, and automation cells where space is at a premium and protection needs are computed at low currents. Key compatibility considerations include use with Siemens low-voltage motor protection kit configurations and compatibility with standard 500 VAC networks; installation typically requires appropriate enclosure rating and safe wiring practices per IEC 60947-3 guidelines. This model delivers straightforward protection within a compact footprint, helping to simplify motor protection schemes while maintaining clear, fast tripping when faults arise.
