The 3VA2063-5JP32-0AA0 is a 3-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 neutral conductor protection optionally available via an external current transformer, configurable up to 160% of the rated current. The breaker uses nut keeper kit terminals for secure high-current lug or busbar 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 L-trip delay time (tr): 0.5…25 s with I²t characteristic for precise coordination with downstream devices.
• Neutral conductor protection optionally available via external current transformer, adjustable up to 160% of In.
• Integrated communication function for remote monitoring and data exchange (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).
