The 3VA2063-5JP46-0AA0 is a 4-pole molded case circuit breaker from the Siemens SENTRON 3VA2 series, engineered for reliable 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 robust frame clamp terminals for secure high-current connections in 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 communication capability for remote monitoring and data exchange (Modbus TCP, Modbus RTU, PROFINET, PROFIBUS via external modules).
• No ground-fault protection — designed for systems where earth leakage is monitored externally or not required.
• Full range of modular internal accessories: motor operators, shunt trips, undervoltage releases, auxiliary contacts.
