The 3VA2063-6JP36-0AA0 is a high-performance 3-pole molded case circuit breaker from the Siemens SENTRON 3VA2 series (IEC Frame 100), distinguished by its H-class breaking capacity of 85 kA at 415 V. Equipped with the advanced ETU550 LSI electronic trip unit, it provides comprehensive overload (L), short-time short-circuit (S), and instantaneous (I) protection—making it the ideal choice for main distribution boards, bus couplers, and industrial installations where fault levels exceed the standard 55 kA (M-class) rating. Neutral conductor protection is optionally available via an external current transformer, configurable up to 160% of the rated current.

Core Protection & Functionality

• Electronic trip unit ETU550 (LSI): L-trip Ir = 25…63 A (I²t characteristic, tr = 0.5…17 s).
• Short-time short-circuit protection (S): Isd = 0.6…10 x In (tsd = 0.0001…0.4 s).
• Instantaneous short-circuit protection (I): Ii = 1.5…12 x In (95 A…756 A).
• Neutral conductor protection: optionally available via external current transformer, adjustable up to 160% of In.
• Integrated communication capability for remote monitoring and data exchange (Modbus TCP, Modbus RTU, PROFINET, PROFIBUS via external modules).
• Integrated display for measured values and integrated measuring function.
