The 3VA2063-5JQ46-0AA0 is a 4-pole molded case circuit breaker from the Siemens SENTRON 3VA2 series, equipped with the advanced ETU560 LSIG electronic trip unit. In addition to standard overload (L), short-time short-circuit (S), and instantaneous (I) protection, it features adjustable ground-fault protection (G), making it ideal for systems requiring selective coordination and earth fault monitoring.

Key Features & Technology

• Full LSIG protection: adjustable long-time, short-time, instantaneous, and ground-fault trips.
• Ground-fault settings: Ig = 0.25 ... 1 x In, adjustable time delay tg = 0.05 ... 0.8 s; can be switched off.
• Adjustable neutral conductor protection (OFF, up to 160% of In).
• Integrated display for measured values; optional communication via Modbus TCP, RTU, PROFINET, PROFIBUS.
• Compact design with modular internal accessories (auxiliary switches, shunt trips, etc.).
• Available mounting versions: fixed, plug-in, withdrawable (fixed mount on 35 mm DIN rail in this model).
