The 3VA2063-5JP42-0AA0 is a 4-pole molded case circuit breaker from the Siemens SENTRON 3VA2 series, engineered for reliable line and system protection in low-voltage power distribution. Equipped with the ETU550 electronic trip unit, it delivers precise LSI protection — adjustable overload (L), short-time short-circuit (S), and instantaneous (I) protection — with fully configurable neutral conductor protection adjustable from OFF up to 160% of the rated current. The breaker uses nut keeper kit terminals for secure high-current lug connections in industrial distribution panels.

Key Protection & Functionality

• ETU550 electronic trip unit with LSI protection: Ir = 25…63 A, Isd = 0.6…10 × In, Ii = 1.5…12 × In.
• Adjustable neutral conductor protection: OFF or 40%…160% of In, configurable via front-panel settings.
• Integrated LCD display for real-time current, voltage, and energy measured values.
• Optional communication: Modbus TCP, Modbus RTU, PROFINET, PROFIBUS (via external modules).
• No ground-fault (G) protection — designed for systems where earth leakage is monitored externally or not required.
• Available mounting versions: fixed, plug-in, or withdrawable (fixed mount on 35 mm DIN rail in this model).
