The 3VA2063-5JQ36-0AA0 is a 3-pole molded case circuit breaker from the Siemens SENTRON 3VA2 series. Equipped with the ETU560 electronic trip unit, it delivers full LSIG protection – adjustable overload (L), short-time (S), instantaneous (I), and switchable ground-fault (G). The neutral conductor protection can be configured up to 160% of In via an external current transformer. Clamp terminals enable quick, secure wiring in distribution panels.

Key Protection & Monitoring

• LSIG trip unit with programmable ground-fault: Ig = 0.25…1 × In, time delay tg = 0.05…0.8 s (can be switched off).
• Adjustable N-conductor protection: OFF or up to 160% In (external CT required).
• Built-in LCD display for real-time current, voltage, and energy values.
• Optional communication: Modbus TCP, Modbus RTU, PROFINET, PROFIBUS (external modules).
• Integrated power/energy measurement for energy management.
